Stop bitcoind, copy your wallet.dat, delete everything else in the .bitcoin directory, put the wallet.dat back in, and restart bitcoind.

This indicates the version of Berkeley DB compiled into your bitcoin client is not the same version as the one that created your database files. You can get rid of those files, convert them, or recompile bitcoin with a different version of Berkeley DB.

1 more thing when your setting up the bitcoin.conf what are you suposto put in it? like the namecoin one all i put is

rpcuser=*****
rpcpassword=*****
rpcport=8336
daemon=1
server=1

That's about all you need. Though you probably don't need or want to change the port number.
