Ok, you asked for it......
1) ShadowKeeper can change the stats (the short way)
2) Keep on warping into final level in beginning (export and do that again) to get the bonuses (no, you do not have to loss DEX to get magic resistanct).... (this is the long way)
3) As for weapons, try to create item code "killsw01", but this is NO FUN once you start using it.
There are other ways, but I am sure you don't need to learn anymore.

Regarding the above info, use your judgement accordingly.
