First of all, this is definitely the wrong forum.
"Suggestions" is about what you would add/change to the game, not about giving you suggestions about what to do ingame.

That said, what you should do further on depends on what you LIKE to do.
If you like grinding then head over to Western Plaguelands and kill kill kill while gathering rep with the Argent Dawn.
If you like instances you should have a go at the Tempel of Atal'Hakkar (Sunken Temple).
If you like battlegrounds then grind one more level before trying your hand at AV (it's fun ^_^ ).

If you want more spesifics you'll have to tell me a little more about what you enjoy...

Well usaually i quest to get hella xp and items to sell. is there a good place for me to quest or is grinding and sunken temple the best things to do?

[Gormash]

Of course there are places to quest... ^_^
Personally I prefer Felwood at 48-54, and Un'Goro might be a good place as well.
There are also some WPL quests opening up from 50-51 that might be of interest.
