Here's my $.02 (or €)

1) BIKE? Your bike should work fine. I'd suggest looking into some gearing upgrades now that you have a bit more time, but 30 - 40 miles a day is a very laid back pace.

2) PANNIERS? If you are fully loaded with tent, cooking gear, etc. make sure you also get front panniers. My tour buddy had only rear bags and we had constant trouble with his rear tire; not to mention the handling. I used Arkel bags and they were fantastic, and are considered some of the best available. They are heavy and expensive though, about $900 for a full set. Ortleib and Vaude I've read make good waterproof bags, but these come with one caveat: they are waterproof. Anything that goes in damp will be damp when it comes out, and probably smelly. I don't have first hand knowledge of this, but I've read many people who have. I wouldn't imagine you'd be riding much in the rain anyway, and when you're camped the bags will be in the tent. A lot of bags are made with Cordura which can absorb quite a bit of rain before things inside start getting wet.

3) TYRES? I like the Schwalbe Marathon Plus, or Schwalbe or Continental in general. Road tires are best if your riding on the road. Thinner tires roll a little more easily, but thicker tires will be a smoother ride.

4) TENT? Make sure the tent you get is large enough to accommodate your bags. Also try to find a tent that ventilates well; this will keep it comfortable and dry. It will also prevent you from carrying unnecessary moisture weight, and allow clothes to dry from rain/sweat. I carry a Stephenson's Warmlite, but in retrospect it's overkill for bicycle touring. Make a plastic ground tarp for it to protect the bottom from abrasion and puncture. You can find rolls of plastic at hardware stores as drop cloths for painters. Cut it slightly smaller than your tent's footprint, otherwise it will funnel rain under the tent. If your tent needs to be seam-sealed, make sure you do that. Also, the insulation you lay on in the sleeping bag provides no warmth, so look into a sleeping pad.

4b) Yep. Chain it up.

5) HANDLEBARS? I toured with regular straight bars. After awhile, I did start noticing some wrist pain, so I'm going to add some aerobars for the next tour. Changing out to drop style bars may become a huge project. I don't know all the details, but for example a Shimano road front derailleur won't work with a mountain bike shifter and vice versa.

6) SADDLE? I like the Brooks leather saddles. The advantage of leather is it's firm, yet forms to you after a bit, making yourself a custom seat that keeps your weight on the bones. The soft gel type saddles distribute your weight to the soft tissue between the bones as well, which is no good for anyone. Leather saddles require some maintenance though, and must be kept dry. If you do get a leather saddle, put your tent bag over it at night to keep the moisture off.

7) BIKE TOOLS? Spare tubes, spare spokes (ask local shop for proper size), air pump (I like Topeak), spare chain, tire levers, and a chain tool. I'd suggest a few individual tools to fit fasteners for seat post, handlebars, brakes, derailleurs and racks & cages. Should you break a spoke that threads behind your rear gears, you'll also need a cassette lockring tool to get the gears off to replace the spoke. Usually you need to carry a cassette tool, wrench, and chain wrench, but I found a nifty little tool called the Stein Mini Cassette Tool that does it all for almost no weight.

8) SKILLS, Learn the basics of maintaining your rims: how to tighten and replace spokes. Learn how to use a chain tool (very easy, practice on an old chain), learn the simple fixes like replacing brake pads, adjusting derailleurs, etc. Sheldon Brown has an excellent resource, and the book Zinn and the art of Road Bike Maintenance is very good as well.

9) DYNAMO I don't know how it is in Europe, but in the US finding an electrical outlet was surprisingly easy. We made sure all our electrical devices ran on the same size batteries, brought spares and a battery charger. Then we simply found a nearby outlet at the campsite and charged everything daily.

14) CLOTHES? No need to do anything special or excessive - your regular clothes will work just fine. This is what I brought: underclothes and socks (3 pair each), 2 shirts, 1 pants, 2 shorts, thermal top and bottom and rain gear top and bottom. Lately I think I'll drop one pair of shorts and get convertible pants instead, and a sweatshirt instead of the thermals. If you are going to spend money on clothes, forget the cycling jerseys and get lightweight backpacking clothes. GoLite make some very light clothes that are surprisingly cheap right now.

If you decide to bring cooking gear, I'd suggest the Sierra Stove by ZZ Manufacturing - a battery powered wood burning stove. Instead of carrying and buying fuel, you can power your stove with sticks and leaves and such. It runs off a single AA battery that powers a fan. The fan blows air through the walls of the stove then out small holes in the bottom of the kettle - acting as a bellows. As the fire gets hotter, the air being blown in gets hotter and the whole thing burns more efficiently. This works best if you bring rechargeable batteries. Also if you bring non-stick cookware (I'd recommend) get plastic utensils and scour pads for non-stick; this will prevent scratching.
