You've got a good choice in rear light there. It's really bright and really noticeable, someone who passed me once even asked if I was an emergency vehicle. You might want to try looking for the 'Stealth' version; it is supposedly a little better sealed against water. That price is also a bit outrageous... I picked mine up for $14 Canadian, including tax, at a local retail store.

I too am looking for a good front light, and have heard a lot of good things about the Deal Extreme flashlights with a bicycle mount. I don't remember the name of the lights, but if you search for Deal Extreme you should be able to find the thread about them.

I'm currently looking for a pump myself, but I'm considering a Lezyne Micro Floor Drive; I've heard only good reviews about it so far.

Saddle bags are pretty easy to remove, you can just undo the straps and walk off with them. If either of you are adept with a needle and thread (or a sewing machine!) you can make something like a bike burrito (http://www.bikeburrito.com/). I made one that holds my 15mm wrench, spare tube, tire levers, allen wrench set and an energy bar, I just put it in my backpack when I lock my bike up outside. It's also small enough to fit in my pocket with a bit of squishing if I leave my bag at home for whatever reason.
