I'm kind of in the same boat. Jailbroke my iPhone (4.1) and iPad (3.2.2) and have been thinking about upgrading. What I know:
1. Jailbreak exists, but it's tethered. That means when you power off your device, it won't turn back on without hooking it back up to a computer with the JB on it. There recently has been a demo by the Greenpois0n people with an untethered 4.2.1 JB, but it's not out yet. BTW, power off means holding down the top button for several seconds and sliding the slider that says 'slide to power off'.
2. I haven't upgraded a JB yet, but one thing I've heard is that there's specific steps you want to take (possibly depending on the tool). The downside I've heard is that you'll lose about 500MB of accessible memory each time you upgrade if you do it in the way you said. Something about the memory used by the JB isn't recognized by the official iOS, so it thinks that storage space no longer exists.
The teathered part of the JB kept me away, but if the untethered JB comes out, I'll really have to think about it. I say if, since 4.3 should be out soon, and I could see them waiting and not burning an exploit for 2-3 weeks of jailbreaking.
