the #1 benefit is it turns your old gear that you can't convert to materia into something you can sell and usually for considerably more than the GC Seals that you would get from turning them in.

best classes mostly depends on your jobs.

GSM is good for everyone, LTW is generally decent for most. WVR especially good for non-tanks/DRGs. ARM is decent for tanks and DRGs.

BSM, ALC, CRP are all fairly difficult.

FSH is good for anyone that would fish.

there are some stretches of levels that are best done by buying stuff from vendors. it'll cost money leveling but if you keep it up so that you can desynth current expert dungeon gear you should make all your money back and more.
