When reading books to gain skills, do you have to read through the entire book to gain the skill, or will simply opening it give you the skill gain?
I haven't found any books that have given me any immediate benefits, so don't know if I haven't stumbled across any, or if I'm supposed to actually be paging through the whole thing.

No you don't. You merely need to open the book to the first page.
You should read the whole thing though. The Lusty Argonian Maid is quite a ripping yarn.
