I'd go with Fortify Light armor, Fortify One-Handed, fortify block, and possibly Fortify Health/Stamina if that's a problem. You will go through a lot of gear as you keep levelling but mostly just pick what you think will be most useful.
As an aside, carry a locket or ring of waterbreathing on you for those occasional times you have to do a lot of swimming. Only weighs .3-.5 ounces and can save you some headache.

Oh, also, enchants that mitigate spell damage are helpful when fighing mages, witches, etc.. Fire and electricty if you're a nord. Otherwise have at least one ring/sheild that has a healthy mitigation of all three direct-damage spells.
