will I still be able to hook the phone up to iTunes on my Mac for uploading of songs, etc or will that relock it?

Yes, you can use a T-Mobile SIM card on an unlocked iPhone. You can also sync with iTunes.

Remember to get a data plan so you don't get owned by a data bill in case you accidentally tap stocks or weather (the only programs on the iPhone which uses the internet right away as opposed to the other programs where you can still exit before it does anything).

You won't be able to update the iPhone, however. If a new update comes out, you'll have to either restore the iPhone, then reunlock it, or you'll have to wait until an update comes out on Installer...or you could use pwnagetool which still restores the iPhone.

I believe those sims are different..check the links, sims card can be removed, but its not the sim card I have and I have tmobile, no way that would fit in my tmobile phone.
