Desperately awaiting replys. I am afraid to begin the game out of fear that my character will suck and or not be fun!!!

It's just different, and i am not use to it.
I am thinking I want my character to be a melee character. How well does that work? Should i be sword n board, 2h, or dual wield?
If my main is a melee, should i make my dk be a archer?? Will he actually be helpful if he is an archer and not a melee??
ps: I beat fergus without adding any stats, and now i am level 10, with no stats allocated playing on normal. I got the gist of combat down i guess, but I just need a little general information on Warrior, Mage, and Archer classes, as well as Death Knight tips.
I guess I am just going to make a second save and continue playing for right now.
Also, big question I need answering. If i remove a skill, does it give it back to me so i can readd it somewhere else? If so that will make the game MUCH simpler, and I wont worry as much. As well as, is there a dupe trick too?? Cause I can just dupe the gold so i can afford it if i need to. (Not big on cheating, but gotta do what ya gotta do lol)
