Anything I need to know prior to breaking the warranty seal, and nuking my PS3's interior with compressed air? Any tips are appreciated.
I suggest having a tray and set the screws aside in the order you take them out, so you don't get confused reassembling. If you're replacing the thermal paste, don't go crazy with it. Also, if you are trying to separate something and you really have to force it, then stop. It's overall not to bad to disassemble; well better than the old 360 (pain in the !@#). Following a guide can help too.

If it is not under warranty anymore... Why are you so worried about opening it up. It is pretty much no different than opening any other electronic product. Just make sure it is unplugged from the wall outlet and open it up.
With your bad back, I don't think you should be picking up any girls. I went ice fishing the other day and all I caught was a cold.
