How can I clear up this negative balance in Multibit? I've reset the blockchain already.

That's not a "balance".  That's a transaction.

It indicates that 0.0001 was "subtracted from" whatever your balance was.  Your balance is found elsewhere in MultiBit.

So if I highlight that -.11 and click on "Show transaction details...", what I see is that it cost me 11 cents to transfer nothing; the original balance I was trying to transfer is 11 cents less than when I started. I assume that's because I: 1) didn't figure out the correct way to set up a new address, or 2) tried to transfer the entire balance.

The -BTC0.0001 is the transaction fee, which is the net debit to your balance. The gross debit (which I'm not sure if MultiBit has an option to show) is the transaction fee plus whatever amount you transferred, but since you transferred it to yourself, that amount is also in the credit column, so it balances out, leaving just the fee. Credit - debit = fee = -BTC0.0001 net.

So if I wanted to empty an address, I would send everything /except/ BTC0.0001 to the new address?

And if I understand all the security measures I've read, any time I receive bitcoin, I should only use each address once, and transfer received BTC to a new address generated by my computer, right?
