have you A. made sure nothing on your sd card is causing this.
B. tried turning of tf3d for a few boots?
c. tried re-installing the default phone canvas?

I recommend not using tf3d, but to each their own..
it does sound like you installed a bunch of stuff that may not be playing nice with each other, or are all trying to load and access hardware during boot, causing the important stuff to get hung up.
if you really want to avoid a referb, you could try some custom roms, or just unlocking/relocking the phone may trigger good effects, but your hardware may be on the fritz too.
