Human fighter is definitely one of the easiest characters to begin with. The biggest challenge is lack of skill points if you have a low INT score. Your Spot and Search are likely not very good also. I've had success adding 2 levels of Rogue to give me better Spot and Search, plus some lock and trap skills and Evasion (if wearing only light armor). It's a trade off, but the choice is up to you. If you plan to play mainly in a group, then the rogue skills are not really necessary. I find them helpful for solo play.
