FOr the incredible is there a recovery program like SPrecovery? Are they similar and can you use RSD lite to put it on?
No there is no Sprecovery but there is ClockWork recovery, which while in recovery looks almost and acts the same. It gets installed when you use the unrevoked tool automatically. As for RSD, HTC uses a .exe called a RUU. You cannot root with the now available RUUs out now like you could on the droid with RSD. The unrevoked tool is the simplest way to root and get a recovery.
