First... this depends on what version of TSVN you are using. I don't see that you mentioned it.

Basically, you need to merge from trunk into your branch. That will bring everything from trunk since you did your copy into your branch. Once your project is good, pass tests, compile etc... commit that merge to your branch.

Then you want to "reintegrate" the branch into the trunk. How to do this step depends on if you are on 1.7 or 1.8.

If you are on 1.8 you basically do that same as before... merge into trunk from branch. Commit to trunk, and continue using your branch.

If you are in 1.7 you need to do a "reintegration" merge into trunk from branch. Commit to trunk... then you should delete your branch. However, you can continue using the branch if you once again merge from trunk, this time merge in the revision that you commited the merge from branch in your trunk. But, do a "record only" merge. Commit that. If you do this "incantation" you should be able to continue using the branch.
