I have German Blue Rams and shrimp. From what I have found so far if the shrimp have somewhere to hide they do ok. Introducing them into the tank was the tricky part as the Rams thought they were food, but as you are going the other way around you should be alright.
If they are larger shrimp they tend to fare a little better and be left alone, that said I watched, two shrimp last night on a walkabout, one was very small and it just cruised on past a Ram with a simple how you doing.
On plants my Rams tend to knock things about a little but not too bad, my Gouramis on the other hand keep eating all my crypts.
hope that helps a little
