Depending on how it's built....heads, cam, etc...it's actually a very good combination. If it's a fairly mild engine I'd stick with a Performer intake instead of the RPM. But Edelbrock did a good job with the RPM intake. You do loose a little on the lower end but you can gain a lot past 5000 RPM. If the engine is fairly mild now but you plan on a cam swap, rear gears, etc then the the RPM intake would be a good choice for the future mods. In all but a VERY healthy 350 the 650 cfm carb will be perfect. I've tried both a 600 and 750 on a decent street built 350 without changing anything else. The 750 was great from 3500 and up but I lost a ton of low RPM throttle response.
Maybe a little, but not much. If you're removing an iron intake, you'd save some weight.

The torker 2 is a single-plane design, so it won't work as well as a 2-plane such as a Performer or Performer RPM.
intake manifold is DIFFERENT for models 1985 and 1988
no
Yes it will, if the 350 intake is from a pre-1987 engine.
The Edelbrock Performer and Performer RPM would be good choices. Also there are a couple Weiand dual plane intakes that would work well.
The intake valves are bigger.
yes
Yes.
Yes, it will fit.
The Chevy Cavalier does have a fresh air intake filter. The fresh air intake filter is located behind the passenger side kick plate.
