You don't need the pay for help from members... if you feel compelled to donate, I urge you to donate to PPCGeeks or the the creator of the rom you're using.
Quick facts: Task29 does not necessarily flash a new radio (there are multiple versions), roms on this forum do not come with their own radio (official carrier roms usually DO), radio or security unlocking will not void your contract or subject you to the ETF, HardSPL unlocking allows for flashing of new roms (not intended for new radios), but with task29, you can kind of bypass this. I have not flashed a different radio using task29 so I cannot advise you on that.
The task29 that I use for my TP2 can be downloaded at the bottom of page 1 here:

And I personally don't subscribe to the idea that the more roms you flash, the more sluggish the device, though errors are thought to common or at the very least possible otherwise.
