For those of you who took the throttle bodies completely off the car to clean them (best way to do so imo) were there any issues afterwards?

I haven't done it but, as long as you don't mess up the electrical parts, I don't see how it could cause a problem. You will have to recalibrate the ECU/TBs but that appears to be a straightforward process. YMMV
I'm guessing that those with problems either did something to the electrical parts or their TBs were dirty enough that the engine had to do some re-learning after cleaning.

I'm with you on cleaning with the TBs removed. If they are dirty enough to need cleaning there is a risk of moving dirt into the manifold and engine. If I were cleaning them proactively (eg, every thousand miles), I would probably do it with the TBs installed.
