Update:

So I went back and asked about the cog, lockring, and TT levers.

My LBS says it already has a lockring and cog. But it will cost a total of $60 for the levers (cables, housing, installation, and the levers). He can no longer get the 2009 in the size and color scheme I want but he has offered a 2010 for $495. I have searched the interweb and everyone else has it for at least $540.

Oh man, what to do, what to do?
