no you will be fine. if you have a mem card in there now you need to save everything to the computer then put it on the 8g. also battery remove is a good thing to do every once in a while. i do one every night
The only setting that gets messed up when I do a battery pull is where my pictures get stored when I use the camera. It always reverts back to storing on the device instead of on the memory card.

Yes very necessary. I have an 8gig sandisk microsdhc I scored for $40 delivered on ebay. Almost maxed it out already
I have 2 full length movies, 1000 mp3s, and just yesterday loaded 850 1mb+ .jpg photos from my wedding. haha I would be lost without expandable memory. You want to be able to store as much as possible and keep your device memory as FREE as possible
