What proffessions should my gnome rogue have? (and if u really wanna u can suggest a talent =D)

Engineering/Mining I guess, most twinks have the best googles and items they can use.

Engineering for the goggles and possibly other trinkets. Jewelcrafting for the BOP trinkets. All other professions make BOE items you can just buy, with the exception of some items, mostly around level 70.

engineering and minin cause u can get the goggles and u can make trinkets that wen u get polimorphed u can disspell it
