New bike shifting woes - what's the deal???

[RolliePollie]

I need some expert advice. I've had my new Madone for almost 2 weeks and have ridden her about 175 miles. She's already been back to the shop twice for derailleur adjustments. I just got back from a ride and the same problems are back. I'm getting really frustrated and I don't understand what's going on.

I have a triple with 10 in the back, all Ultegra except I think the cassette is 105. So I'll call the biggest cog in back #1 and the smallest #10. #1 is fine, but #2 and #3 skip and jump back and forth between each other. The chain won't engage on the cogs and I cannot use them at all. 3 and 4 do the same thing in the small and middle ring. I can get it to latch on to 4 if I shift through to 5 and then shift back to 4. Then it's fine through 10. This is just not workable for hill climbing because I have to quickly skip from 4 through 3 and 2 and I lose all my momentum. Plus there's lots of clanging, banging, clunking and other horrible bad shifting noises.

So just now, I turned the bike upside down and counted as I shifted through all the gears, starting at 10. But it appears I only have nine gears. It's skipping between 2 and 3 on one shifter click, plus the first shift up from 10 to 9 does nothing.

Is the indexing messed up? How do I get my LBS to fix this? Am I just a huge idiot and I'm doing something wrong? The last time it was in the shop, they said it shouldn't be going out of adjustiment like this, so I'm assuming this is not normal new bike behavior. Please help!!!!
