I don't bother with cleaning primer pockets on pistol ammo but I'm not shooting bullseye matches.

Not necessary with carbide dies but I've found a light spritz of Hornady One Shot lube makes life easier when sizing.

Watch... somebody is STILL gonna jump in with "You don't need lube with carbide dies."

If you don't already have 'em go ahead & buy a few combo wrenches of the proper size. Adjustable wrenches will just make for frustration.
