Just chiming in, on windows, you need to create a bitcoin.conf file and define your rpc username and pw in order to be able to launch 'bitcoin.exe -daemon', then you use the username and pw you specify here to call diablo's miner
rpcuser=username
rpcpassword=password
likely located in C:\Users\[your win username]\AppData\Roaming\Bitcoin\bitcoin.conf in win7
And I cannot recall where that would go in XP off hand, but wherever the rest of the bitcoin stuff is stored
Also, I don't think that java is appended to PATH by default, so you will probably want to add that as well to use 'java' from the command line
C:\Program Files (x86)\Java\jre6\bin
