If you have no trouble keeping the pirates at bay, the Zygor guide Tuco mentioned recently is damn good. Unlike Carbonite, Questhelper etc it doesnt steal your megahurtz, it simply gives you arrows to follow to get from A to B as fast as you can stand but also has handy info on what exactly you need to do, where the mob/npc/doodad etc is. I'd only recommend it if you are on your 18th level up etc as it pretty much makes it even more whack a mole than it already is. The 21st April version runs fault free for me, the one linked before misbehaved rather badly with its custom version of Cartographer.
If you prefer to view the scenery a little more then carbonite isn't bad, if you have a beast of a pc and don't mind crashing like fuck in Dalaran (I havent tried it for 2-3 months so might be fixed/better by now) Questhelper is a popular alternative.
If you have a 2nd monitor/pc or don't mind lots of alt-tabbing, simply following Jame's level guides is a good option as they are very well written and pictured :
