<p>The firstbits address on the front of the coin (once fully resolved from blockexplorer) is just like any other address right? I can buy a 1 BTC Casascius physical coin, copy the address, bury that coin in my backyard, and use regular transactions to keep increasing its value?</p>

What you see on the front of the coin is not the Firstbits. It's simply a fixed number of first characters of the address. The only robust way to deduce the full address from what you see is Casascius' records, https://www.casascius.com/fulllist.txt. But yes, once you find the address of the coin, it's a normal address you can add more coins to and access them with the private key within.
