With weapons you are a bit restriced but the straight sword category is really strong. I suggest Broad Sword or Longsword, though the Mace is very handy as well if you like the playstyle.
For spells I prefer Chaos Fire orb over Chaos bed Vestige. Warmth is not worth it - neither for healing nor for the 2 slots. So you will be better of using a healing miracle. With 5 slots you could go with: Chaos Fire Orb, Chaos Bed Vestige (situational), healing miracle and tears of denial.
I prefer not to have to buff my weapons mid-fight so I go with chaos- and dark infusion as main damage source and a raw and blessed infusion for resistant enemies or respawning skeletons.
Alternatively you can of course use a raw infused weapon and buff it with Carthus Flame Ark or Dark Blade.
If you use Darkmoon Ring you can of course also implement more spells - including dark magic. The things I would aim for personally there are Dark Fire Orb or Dorhy's Gnawing.
