Any barrows right now would be a good choice for you. It's amazing armor for cheap price. Upgrade to a glory, get better defence with a shield (DFS usually because of it's epic defence and strength bonus and price), Barrows Gloves, and you should be good. If you can afford curses in the near future, I do suggest getting those. The tables will turn from getting destroyed to destroying. If you go with a chaotic, get the rapier first, CLS second. Rapier is useful for everything while CLS is only limited to bossing usually because of it's slow, but heavy attacks.
