Is there AMBER/GLYCAM integrated force field presently available? I have read through the basic and membrane tutorial but am still lost.

I don't know whether there are force field files available, but I know plenty of 
people have posted GLYCAM questions to the list, so presumably there are.

The biggest issue you'll have is the branched nature of these compounds. 
Getting a sugar attached to an amino acid will require modification of 
specbond.dat to create the non-linear bonds.
