If you have enough clearance, run a Purolator Pure One PL3001, regulator Purolator L3001, or Wix 51515. That's the full-length version of the "shorty" used on many Mopar LA-block engines. You pick up about a half quart of oil volume and double the filter area over the shorty.
As for oil, Valvoline MaxLife has served well in my Dad's 92 Dakota 5.2. But pretty much any of them will do. I like the Mobil One lineup, so I'd probably go that way personally. I'd do a few short OCIs during clean-up, then forget about it.
