Assuming your 8n runs as it should:

a) 5 foot will be the max that you will want for a bushog.

b) Will need to run somewhere around 3/4 throttle or slightly above above to maintain your needed 540 PTO RPM

c) Unfortunately 1st gear on the 8N tractor will be too fast in really heavy/thick stuff. Throttling down to reduce your ground speed only further multiplys your already marginal power problem. (Although inferior in many ways to your 8N the older the 9N/2N had a slower 1st gear that helped with bushhogging heavy stuff. I think that 2nd gear on the 9N/2N is even slightly slower than 1st gear on the 8N).

d) Good advice on getting the over-running clutch if you do not already have one. $65 is a cheap investment for the measure of safety that it will add. It will allow you to stop instead of the blade inertia jerking you forward when you clutch. Helps protect your driveline too.

e) Sharp blades help with marginal power.

f) Some of the King Cutters have a restrictive deck outlet for the material discharge exit in order to mulch things up. Enlarging this outlet can sometimes help margianl power tractors by kicking the material out from under the deck faster which in turn consumes less power. Of course the material will not be shredded up into quite as small of pieces.
