I love my new encore and plan on hunting with iron sights this season and need to outfit my muzzleloader without spending a fortune

I need to get all the accessories and have a few questions about you opinion of the encore and supplies:

Which 209 primer ?
Sabot/Bullet?
powder/ pellets?
Best loads/combinations?
Tools to load/ clean?
Lube?
T handle?
hunting carry cases?
rings and bases?
scope under 300?
What is the major difference between encore/ prohunter/endeavor?
why is mine a "magnum"
Place to buy a good rifle barrel?
What is the going price for a new encore?

Thanks for any information that you wish to share
