It's been a week; but in the absence of anyone really answering your question crash, I'll weigh in. If you stop back by, I hope this helps.

Jigsaw (or scroll saw if you have one) is probably your best bet.
You can use a drill or a dremel "plunge cut" to start your long cuts with the saw. The corner curves there are probably a bit tight for a jigsaw, but you can try it. Just go slow, and stay inside the lines. Layout what you want to cut on masking tape, and use a half-round file to take your cuts out the lines.
Aluminum is pretty easy to file, it's fairly soft. Just remember, its a lot easier to take a little more material away than it is to add it.
