ummmm, not quite sure what you are looking for here... 16x verb and burn at 8x (debateable whether or not to burn at 16x) and you can expect to be able to burn many 100's with that burner? Each burner is different.
as for + or -, if you have a choice go with -. As far as I know and someone can correct me if I'm wrong, they are more compatible with older machines and generally give you less problems.This thread here should answer a few of your questions.
I would go with +Rs; for the main reason that they can be booktyped to DVD-ROM(if your burner is capable). They are more recognizable to stand alone players this way. -R media is cheaper online, but - and + R are the same price in B&M stores. Try both and see which your players like best.
