Pacific Northwest Gardening: Help with trilliums and hardy orchids. Please!, 1 by Rarejem

OK all of you woodland plant lovers that brought the fact that hardy orchids exist last spring... I need your help! I have just aquired my very first hardy orchids, as well as my first "unusual" trilliums, and I would love some advice before I decide where to plant them. I am very excited about my new babies, and want to give them the best chance of survival.

What I purchased:

Epimedium grandiflourm "Lilafee"
Epimedium grandiflourm "Red Beauty" aka E. "Yubae"

Trillium luteum
Trillium erectum
Trillium catesbaei
Trillium grandiflorum
Trillium cuneatum

I have plenty of humusy soil, but most is in pretty good shade. Is that OK? I also have slugs the size of small cats that tend to decimate anything in their path. Our natural trilliums survive with a minimal of slug damage... how do the more exotic varieties fare? And how do the epimediums do with slugs?

And as long as I am asking for advice, I also picked up some ornamental Rhubarb.... does anyone grow these?

Rheum palmatum var. tanguticum (supposedly gets quite large)
Rheum "Ace of Hearts"

Pixy, I think that my garden visit to your house last summer is responsible for my almost overwhelming desire to add more red/burgandy foilage to my world!

Thanks for any help you all can give!
