Your resistances are not very high, it could be that the dragonriders/demons give you a bad time. I had my resistances up to 200, specially spiritual res. (I'm a very defensive gamer <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />). There is NO maximum for res. You will be attacked by fire, lightning and freeze.
Which armour/item is NOT charmed, how many slots are free? You can buy gold charms from Kroxy or get them by fighting the imps to boost up res.

Reputation is not important in the the Wastelands - but if you go there: No way back, so no completion of unfinished quests.

Your lvl is ok.
Give it a try and make a different save before - if it does not work, you can reload, hm? As I said: I'm not sure if 50 res. is enough against dragonriders/demons - let alone the Big Baddies in the enddungeon.
