Yes, you can use the droid incredible with the straight talk.
The biggest difference between the Droid Incredible and the Incredible 2 is in the design. Incredible 2 has an aluminum design while the Droid has more of a plastic feel to it.
There is no Droid Thunderbolt. There is the HTC Thunderbolt. I would recommend the Droid Incredible 2 which came out in the past month. It dose not have 4G like the HTC Thunderbolt but It is far more powerful than the Droid Incredible and will be worth your while.
No
I would prefer to get the Incredible because (from my experience) the Thunderbolt is not as good as it looks.

Both phones are really nice 3G Verizon Droid phones. The Droid X2 is newer than the Droid Incredible 2, and in my opinion a little nicer. However, it might depend on if you like Motorola or HTC better. HTC makes the Incredible 2 and Motorola the Droid X2.
The Droid Incredible is better than the Droid because it is faster, its lighter without the slide out qwerty keyboard. (The keyboard on the Droid sucks anyway.), and HTC sense in better than stock android.
When it comes to specs, innovation, and the latest smart phone technology, go with the Droid Incredible 2. Its specs mirror the HTC Thunderbolt, though the Incredible 2's battery lasts way longer. The only reason to get the Droid X is the price. Go with the Incredible 2.
Droid X is much bigger. Better. Faster.
