Maybe 10. Big ticket on sbc heads is to open up the exhaust ports.

Full length will give you the most (As Jim stated up to 10 or so). A good H or X pipe for balance is a great way to go as well.

Mids or shortys in my opinion are worthless. But again, my opinion not fact.

Nope. if you are running mid or long tubes, I consider a 3 wire heated O2 sensor a must.
