Need to replace an inner wheel bearing on my 69 b-body with 11 inch front drums. Never done this before.

couple of questions:
1) I know you need to replace the wheel seal anytime one is removed. so since it is being replaced can I pry out the old one with a screwdriver or do you need a seal remover to avoid damaging something other than the seal permanently? Never pulled one so not sure how tight they are in there.

2)I was going to order this wheel bearing

Was unsure if i need this Wheel Bearing Cup - Inner - Front Wheel as well?

3) Can the new grease seal be set in place without buying a seal driver? seems it could seated squarely as there is lots of room behind the drum to work with

Figured I would check so I can order the parts today before disassembling and replacing this weekend.

TIA
