Overexposed means too much light
It will look whitewashed, if you are familiar with the term
Sorry about not answering the film part, I'm pure digital! =D

iso100 film generally gives better saturation and finer grain than iso400. but since it's less sensitive to light, that means shutter speeds you get with iso100 are slower. this can be a problem indoors or at night, because you may get blur pictures from your hand shaking the camera during exposure, or from the subject moving. you can get iso100 film from shops like konota and ruby in the peninsular plaza/peninsular shopping centre area.

lots of differences between slides and negatives, may be better if you do an internet search. some basic differences:

negative film is generally more convenient, both to find/buy, shoot, and to develop and print. all photo shops can do it. this is the stuff most people use.

slide film tends to be more expensive and harder to find. not many shops can process them these days. when you get them developed, you get slides, not the usual negative strips. slides can be viewed using a lightbox/table, slide pojector, or scanned and printed. there are other ways to get prints from slides, but these are uncommon and expensive these days.

negative films have a lot of leeway for mistakes with exposure. you can still get an ok print even if you're a few stops off. with slides, you have to be much more accurate.

so, why slides since it's so much trouble? i'm not the best person to ask, since i'm not much of a slide shooter. but the usual reasons given are that colours on slides are nicer. also used to be that slides were used for a lot of commercial work, but not sure that applies as much these days.

hope this answers some of your questions.
