Is there anything else I really need to know?
And what should I expect for a first-time litter?
Don't harass the doe when she's due/kindling/has kindled. Just let her do her thing and only intervene if absolutely necessary (kits born on the wire, etc). Give her a treat when she's completely finished having her kits to munch while you check for any dead/problems/etc. (It can take a day for the doe to nurse the kits, just fyi) Then, put them back and leave her to it.
I do find that does handle routine best, so I find it very helpful to give treats and check the nestbox daily starting a few days before she's due.
With newborns I check once a day to make sure they're getting fed until they've got their fur in, then I start handling them a little at a time. As they age, I handle them more often.
Like Mysunwolf said, a lot of it comes from first-hand experience, but asking questions is a great way to start out
