I have recently experienced a similar issue with my new Barb. Here is my take on the low and mid levels and my solution.
Levels 1-7 Rage isn't a necessity because your STR is exactly the same as any fighter of the same level therefore you can just drink a Bull Strength pot and go S&B and kill right along side everyone else with a decent AC.
Levels 7-10 Buy some Barkskin pots, get a protection item or buy some SoF pots, use them liberaly and keep a S&B weapon set up in case stuff gets too nasty or your HP gets to low and you need a copuple extra AC there while you drink some repair pots.
Levels 10-13 Keep the BS pots and SoF pots going, at this level the paralyzers come available and are **** nice to have around. Get a nice Greataxe or any available 2 hander and reage up drink a haste pot and give'em hell!
Levels 13-Cap By now you should be grouping with almost full parties or at least compotent people so the acquisition of some nice raid gear and other things that make you more healer friendly should be much easier.
Hope this helps a little for ya.
Edit: Never ever use Fearsome! You can't kil stuff that is running away effectively imo.
