The thing sticking out on the left side of the steering wheel is the turn signal switch.
The reason the clutch and brake pedals are so small is there are rubber covers that go over them. You can get those from any of the vendors.
There have been numerous threads posted here regarding what to do, and what to check before attempting to start it---the most important being to drain and clean the gas tank. A search of the forums should turn up plenty of good information.
As far as price--obviously whetever two people can agree upon, and the cheaper the better!

I would probably try to stay toward the lower end of the range you mentioned.....but that's just me! Whatever you're comfortable with is a fair price. You'll end up sticking a fair amount into it just making it roadworthy, plus whatever improvements and fixes you do after that.
Looks like a fun project. Good luck with it, and keep us posted!
