How much does the bike really matter?

First off, congrats on your training and commitment. I wish I had the time and I will live vicariously through you and you accomplishments. You have a great opportunity to learn from other racers and pick up on what matters. You could go out and buy a $12,000 Pinarello, but if the bike doesn't fit you are not going to be productive. Obviously all the weight weenies will tell you wheels, tires, yeah, they make a difference, but it's still the engine. I'm sure in the racing arena, you will be surrounded by dream bikes, it's all about the dollar bill. It also sounds like if you are outgrowing your bike, your fit is what may need to be adjusted. My advice as recreational rider with friends doing Ironmans, keep you bike and ride the piss out of it. Lighter tires, yeah thats a start.
Take a look at the new Bicycling 2010 buyers guide. Your timing is perfect and the economy being what it is, there are more mid-range great carbon, ultegra bikes cheaper than ever. Start looking, do your homework. I've seen folks on hugely expensive bikes and they can't ride, and I am more impressed with the dude or girl that hoofs on an older steed!

Wow, thanks for all the quick replies (and compliments!).

It sounds like my first step should be to evaluate whether my current bike will still be able to fit me. It felt pretty big when I first got it, but by last summer, it felt perfect. After my bike fit, they cut my stem down a ton. They also tipped my saddle back a little to alleviate numbness in my hands, but I noticed some soft-tissue pain after that. I was told that it was pretty much a trade-off between the two problems, which makes sense, I guess.

I've mostly just ignored the occasional soreness, but now, with my growth spurt, it feels really awkward to be on my bike. Both of my achilles tendons have been bothering me, and I've noticed some new knee pain as well. I'm not sure if my torso has gotten longer, but I know that my legs have for sure; all of my long pants are 2-3" too short now.

I did buy new tires today, so I am excited about that and hoping it will help a little! My team has a deal with Neuvation, so I could probably get new wheels through there. I haven't noticed a problem with my components (all Shimano Sora), so I think I'll stick with them?
