First, some bad photos to help demonstrate what I'm working with and then on to a few questions...

A shot of the shower rods in the mirror and the weird wood stuff beside the sink/mirror:

Bathroom window:
My main questions are in bold, for those of you who feel like skipping.

The color scheme I'm planning to use is basically lots of white, with aqua/turquoise and yellow, and accents of orange. Essentially the colors of old maps and rubber ducks because my "theme" is a mix of travel and ducks. (Think ducks with luggage labels mod podged on, and train cases storing bath stuff. I had a duck bathroom before but I wanna branch out. Heh.) I completely forgot to take a pic of the shower curtain but it's white with ducks and little dusty blue accents and trim. I got some pretty glass tile coasters from the dollar store that I plan to attach to the wall somehow beneath the mirror and above the sink, if possible. They're blue and clear. The walls will be white, probably with either aqua or orange trim. The toilet is a pretty retro yellow color and very rounded.
So. First of all, apparently this bathroom has been through a bunch of incarnations. A weird medium blue, a pink shell wallpaper, plain white, off white, and once the whole thing was apparently a weird dusty rose/mauve color, possible when the shell wallpaper was there. Before I started ripping everything apart two walls were a weird mauve color and the others were a dull off white, with no reason for the difference and so barely noticeable that my bf didn't realize it was pink till I started exposing the white beneath it. Most has come off easily but pretty much all that you see that's still not white is refusing to come up even using a razor blade. Do I just need to try harder to scrape it all off or will it be okay to just sand it down good and prime it? It's kind of a different texture than the exposed wall. It's also not all the same color, with a lot of off white, then white, then mauve, then blue lines running through it. Would one coat of primer cover over all the colors so they wouldn't show through white paint?
Secondly, I really rather like the wood grain that I discovered beneath all the layers of crap on the cabinets. The problem is I've so far had to remove the paint using an exacto knife because my paint scrapers are too thick to fit beneath the paint and paper. Would it look stupid to just have those two cabinets that I've already begun have a stained wood grain and then paint the others? Or do I need to finish what I started...?
I'm thinking a nice warm but light orangey stain, or perhaps just white washed. (Unless they make an aqua stain. Heh.) Which do y'all think? I'll probably do the same for the window.The sink base, to me, is an eye sore and I hate it. Opinion poll: Should I paint the sink base or make a funky skirt for it?
The weird recessed area next to the sink is basically just plywood. I think it may once have held a water heater of some kind in that space and then they boarded it up. What I want to do with that is cover it with a collage of old maps. Do you think the collage of maps will be too "busy" for such a small space? Since there will be cases and ducks and such.
Also, I'll hopefully be exchanging that wooden cabinet with something else, and some shelving or tiered table will be going beside it more than likely. I had stacked crates there before cleaning out the room.
Also, any advice on the prep stages of painting will be much appreciated. Thanks in advance for everything!
