Like for the silenced I would like to know if they modified the contact surface area like a landing pad or O-ring to help reduce the noise level or if they modified the switches.
There is a foam landing pad for the upstroke, no o-rings. The switches are the same, nothing modified except some silenced models have different color stems (purple instead of black).
You can do a silencing mod yourself with o-rings:
http://geekhack.org/index.php?topic=34972.0 It's a lot more work than just popping off some keycaps though. You have to take all the switches apart individually. But at least there's no soldering involved.
Anyone have any information on the weight distribution?
Depending on the model, it would be like this:

Does anyone know where I could purchase a Realforce besides Elitekeyboards or Amazon? Lastly does anyone know where I could purchase the 10 year anniversary model? That model looks pretty badass and if I'm going to purchase a Realforce I think I would like to buy that model.
There's also ebay. And the more costly option of importing from Japan or China if the model you want isn't available domestically.
You'd have to buy the 10th AE used from someone. The ANSI versions comes in variable and all-55g. There's also a JIS version that's all-30g.
Here's a wiki page with all the Realforce models:
