I'm going to put it up on the stand tonight and take a look at the cables, but operator error is not impossible. I watched my shifting closely today and wondering if I'm cross-chaining from the big ring to the 24 in the rear? Could the FDR be pushing the chain down? It wasn't rubbing, but... Oh well, I'll check the cables and it's going in for a check-up next week anyway.
I'm guessing the cable has stretched a bit. In the small cog you might see/feel some slack in the cable under the downtube. If that's the case you can fiddle with it or have the shop do it. Basically it involves either shortening the cable (by moving it at the anchor bolt on the derailleur) or "lengthening" the housing (by unscrewing a barrel adjuster a bit). If it's actually shifting down it's probably best to rest the barrel adjuster/s and re-anchor the rear derailleur cable. Neither of these affect the limit screws, assuming they were adjusted properly, but if you have doubts about anything then bring it to the LBS. If you're mechanically proficient then it's not a big deal. If you prefer to leave the mechanical stuff to someone else then it can be very confusing and frustrating. You could practice a bit on your older bike, but you might run into other things like corrosion or stripped fittings or fraying cables etc.
My teammate has a 105 bike and he upgraded it at considerable-to-him expense to get an Ultegra bike, I think a few thousand dollars. He regretted it as it didn't make a huge difference in actual performance. At that point he was upgrading to a 3 I think. He got a pair of carbon tubular aero wheels ($500 from a "planet" company if you will, $700 with tires). He couldn't stop raving about them. The lower weight and better aero made an actual difference in performance.
I tell people with 105 bikes that they should invest in long-term, bike-transferrable stuff (wheels, saddle, pedals, maybe bars) and just wear out the wear stuff (drivetrain, especially chain/cassette). If I was starting over I'd get 105 or Force. I even did a post on my thoughts on bikes equipped with not-quite-top-line components
It seems like you're taking an enthusiastic but sensible approach to the sport. That's great and I hope it's something that becomes a lifelong passion.
