Credit card charges as "bill payments"

I want to be sure I am doing this correctly....

1) I have a bill for AAA Blueprinting for $10 that I have entered into QB 2007 2) I "pay the bill" with a credit card, and mark it as such, so that that the Bill Payment shows up as a transaction in my credit card's registry in QB.

If I make a mid-statement payment to the credit card company, for some round amount that does *not* exactly total up to certain Bill(s) listed in QB (in other words, if I have 3 Bills in QB that total $156 and I make a payment to the credit card company for $100), is there any other "accounting" to be done other than the Bill being marked as "paid"? Do I have to account for ME paying the credit card company?...

thanks...
