900 Parts - to fix, or not to fix...

I've inherited a 900 from my Mom, and I was originally going to sell it. However, it's become a great work car and now I'm a bit more attached, and invested a few bucks in it so now I'm goin to start maintaining it come spring.
I need to get some parts; the small orange blinker lights on the side are busted, I have a front left headlight that comes off and on, and a few other cosmetic/minor issues. Any thoughts on where to go for parts?
Also, I need to fix a peculiar door lock situation. The passenger and rear doors are electronically locked, and I can't unlock them using the buttons or manually. Do you think I can handle this on my own, should I take it to the dealer, or search out a foreign shop here in Detroit?
Thanks for your experience! I'm going to need it...

I have had alot of luck getting parts on Ebay. There are alot of them out there. As far as your rear doors go, look on the inside of the door where the latch is, and see if there is a child lock switch. That could be what is keeping the doors from opening. Good luck.

Just remembered another site that I bought struts from. There prices are much better than the dealer.
