Re: 20/-20 Mon vs Sanctuary on a Javazon?
With 65% to all resists CoH provides, you could easily go with jeweled monarch for more damage. Since you mentioned the rune receipt, I'm not sure if you already have the 'Sanctuary' RW made. Note, that it has quite wide range of resist values (50-70%), thus you'd need a good roll on it to beat e.g. Moser's.
Anyhow, since I don't see any CBF on your gear, 'Rhyme' would likely be your best bet for the moment, until you get Ravenfrost or such. A javazon gets raped badly without CBF, no matter how godly the rest of her gear is. There are a few exceptions, namely cow/Pindle running, where you can get along without it, but don't even think about running Baal or such.
Try to gamble/craft a few pairs of gloves, or (if you have the patience) shop either Anya or Gheed for +3java/20%IAS magic gloves. Thundergod's Vigor and Razortail are both great options for belt, and it depends on your playstyle and goals which one you'd prefer.
