That about says it all...
You use Shimano STI, you will have to change the front derailleur to a road-style one, but no other major changes to the drive-train are needed. You use bar-end shifters and the shifting should still work with the current drive-train, provided that the bar-end shifters either:
1) Match the amount of cogs on the cassette (i.e. Shimano Ultegra bar-ends are 8-speed, and will work with 8-speed rear cassettes).
2) Has a friction-shifting option for the rear cassette, in which case, it could be used with just about any cassette. The front derailleur shifter for bar-ends is usually friction-only, which means that it could be used for just about any derailleur.
