depends on what you'd like. if you pvp a lot then i'd suggest engineering. helps a lot in pvp. keep mining as you'll need it for engineering.

if you want to earn money then drop mining and take up a money making profession....like herbalism.

alchemist is more of a money maker. engineering is more for pvping. can't make much from engineering as almost all stuff from engineering are only usable by engineers.

wow you sure blow your money quickly. buying new gear every level. you gonna hav trouble when you are 60 then, since you never saved up for it.
