Hi Judy,
I too would suggest you get rid of the credit cards, if for no other reason than the one you stated yourself. Having them make them easier to use and what if one month something comes up and you can't pay them off. It starts a bad cycle.
Yes, many people do stop their 401K until they are debt free. I did and allowed the interest to accrue on the balance.
Now, I would only suggest this if you are really going at it to get out of debt, if you aren't you may as well continue to contribute. There should be a timeline where you expect to be able to contribute again. This may also depend on your age and the amount already in the account.
I hope this helps - if you have any other questions please feel free to email me ____@____.com.
