Well, I figure that going over the
User Guide (you could put a copy on your phone too) wouldn't hurt, perhaps more to get an idea about options than for figuring how to do things (although that might help too). In this context you might also want to have a look at the relevant MacWorld
Superguide(s), which I found helpful for other topics.
As to apps, that depends to a large extent on your interests. I could suggest freebies I like that might suit you if you give us an idea to work with.
