The original FF is one of my old favorite games. Try the party fighter/fighter/red mage/white mage. The fighter duo makes the game a lot easier (put them in front), red mage is just generally solid and has key spells (FIR2, FAST, et al.) as does the white mage. You can use HRM with the white mage to deal with packs of undead monsters early in the game. S/he also gets a lot of other useful spells, and there is a point midway through the game where you can get an item called the zeus gauntlet, which when used as an item in battle acts as LIT2. It gives the white mage a good general attack for the second part of the game. There are other good parties of course, but that is a good one to get started with.
Chrono Trigger and FFIV are also great games. I have probably played through CT once or twice and FFIV a few more times.
I never played BoF2 or Earthbound. Might check those out when I have a little more time.
