Yes, Car Rental Companies accept Secured Credit Cards. There are two types of cards. "Secured" and "Prepaid". Prepaid cards will be accepted at rental companies (or will be treated like a debit card). SECURE cards on the other hand are not like a credit card. The rental company has no way of knowing rather the card is secured or not.
All secured cards say "debit", and have a Visa, Mastercard logo, etc. However, as with any credit card (secured or su-secured), they will take a deposit out on the card that covers the rental fee for your expected term. This will not be "charged", but "held" to your card until you return it, at such a time you can choose to authorize the payment to go through or pay the balance with a debit card, allowing the hold on the credit card to release.
2nd part of your question first:
No, it won't hurt you to try and may help you by forcing you to educate yourself about your rights under the law and civil procedure.
As far as "how"; that's a bit more complicated, but definitely worthwhile to pursue. Refer to www.artofcredit.com for information.
You can sue them, but the awards are so little that you have to really pay to do it. If they would make the penalties a bit more hefty, they would quit doing the things they do. They push the envelope because the fines are not that big.
Not that I know of.. What does one thing have to do with the other?
BY PAYING YOUR BILLS ONTIME, KEEPING THE BALANCE UNDER 40% OF THE CREDIT LIMIT. The lower the debt to credit limit ratio, the better. I would try to stay under 25% of your credit limit.
