Is there an easy source to view what the current contract is for any given player.  I guess this is probably a stupid question since most people just know them off the top of their head, e.g. the Jeff Weaver deal is so incredibly bad that no one will forget how much money he's making.... But in the general case I often find myself wondering "wait how much are we paying this guy, and how long is he going to be around.."

I couldn't find anything obivous on the officially un-official seattlemariners.com players pages (which are basically just the MLB.com player pages).  baseball-reference has transaction histories, but that's all.
