I'm doing my whole apartment too next month, before and after pics will be posted later...
I would advise all white trim with earth tones everywhere else.
Light brown, tan paint.. and apply brown speckled stuff over it afterwards with those funky sponges or just splatter it if you're artistic.
Window trim can be dark color, whatever matches your furniture
You can stencil some plants on the wall and have fun with it.
If there is a bathroom, hunter green is nice, with white trim.
In your bedroom, do a squiggly wiggly pattern on the ceiling (assuming it's drywalled and not a dropped one).. girls will like it but it will give you nightmares. hehe
