You can make W/R work, any combination of professions has their strengths and weaknesses ... as a /R you have troll unguent: it's good regen, and it's not an enchantment ... so it can't be shattered/stripped/removed in any way.
If you find yourself dying too much, the /Mo is easiest, but you might also try using /E and using some earth magic (although this will kill alot of your energy) for higher armor/wards/etc.
/Me has your resistance stances (elemental and physical) so if you're fighting something specific, there's a nice +40 armor for you
and lets not forget your primary! watch yourself and dolyak signets are AWESOME armor spells (just ask Racthoh

)
And I would leave the pet, but that's just personal prefrence. Mittens has got me killed on more occasions than i'd like to think about
