Ok... first off calm down. You are getting freaked out over something that is very easy. In fact, once you do it the first time, you'll never worry about it again.
As I said, you are in a much safer position than the person renting as you control the points. There is very little they can do to cause you a problem and even if they did, if you do it right, you'll have their deposit and could still rent their points. Rentals happen all the time with out any problems.
If you want to try it with some of your 09 points, I will be happy to assist you in any way I can.

Read this thread about the taxing. It's a mixed bag of advice, although I found BPMorley's (an ex IRS worker) post especially informative and entertaining. PM me if you want my opinion on it.

Here is a thread on
DVC Rental Contracts - As a Seller, I've only used them once and have never had an issue at all, even with an Ebayer I sold an existing reservation to that I couldn't use due to my wife's pregnancy (she would have been 36 weeks at the time of the trip... literally made the ressie a week before we found out). I've had great experiences with DISers and prefer to rent to them here... Ebay is only used because of the DIS's rule about existing reservations.

Here is the official Rental Primer - This is a MUST READ.
Ultimately, I like renting to DISers with an established reputation... at least 50-100 posts. But I have rented to Newbies too and had no issues.
The biggest thing to remember is you have a while for your cruise. If you want to try doing a small rental, I will be happy to help you in anyway I can. Once you do it, you'll find its very easy...
For me it consists of this:
1) Post the Rental Thread.
2) When someone agrees to the pricing terms, talk with them and find out what they are looking for... ME,
DDP, etc. Call MS and verify availability.
3) Have them do a contract (Ok I'm bad about this step, but best practices state to use one) and give a 50% deposit.
4) Call and make the Ressie.
5) Wait for the confirmation letter, make a copy and mail to them.
6) This is optional, but at a month out, I'll email to see if they need any changes to ME, DDP, etc. Otherwise, that's it.
7) After their vacation, send an email followup... again its optional.
That's it. Seven steps...at most you'll spend 3-4 hours on it... probably less.
