Tsel, one thing to know.
You can solve all Quest for the different Memberships in the Camps.
So, if i go to the Swamp Camp, i was Level 7 or 8.
The rest of hints i can give you are to great spoilers, and i will not write them here.
If you are interested for a step by step Walkthrough, please write a PM to me.
Sorry to hear about your Handycap, but i can say if you play a fighter, you do not need push (in Fightsituation) other Keys as the Ctrl Key.
The rest can be handle by the Right Hand and the Arrow Keys.
You do not need to play with the Mouse, it is allways easyer to Play only with the Keybord.
