Hi Brandon
Great!, another holographer, welcome aboard
For a beamsplitter i'd recommend contacting Dave Battin at the Holography Forum: http://www.holographyforum.org
Dave makes a really nice variable beamsplitter using a PBS cube and a halfwave plate. Get another halfwave plate from him and you're good to go.
For front surface mirrors, try a seller on Ebay: Otas32 (I would have posted a direct link but there seems to be a problem posting direct Ebay links). I've had some of these mirrors and they seem pretty decent. Of course, you can cut them to whatever size you want.
If you don't want to get into developing with chemicals, Litiholo have started to do some nice photopolymer material that looks really promising, it's still pretty expensive though.
Holography is a brilliant hobby, welcome to the journey
Cheers
Jem
P.S. Bob, i've sent you a PM
