I don't mean to disappoint, but if you are taking video or burst mode shots, all you need is a class 6 card. the size of the card is up to you. As long as I can find a major brand on sale I buy it, and save the $$.
FZ-35/38 cameras are a bit picky about batteries. Be sure that, if you select a third party battery, that the seller guarantees that it will work with the FZ-35/38. I carry my camera without a case in a separate pocket in my purse. That way access to the camera is fairly quick and I don't think that further protection is required. That system has worked very well for me for many years.
