I'm confused by your comment about banking them from "last year into this year". It sounds like you have an April Use Year. So are these points Apr 2008 UY points that you banked into your Apr 2009 UY, or were they Apr 2007 UY points that you banked into your Apr 2008 UY? If they were '08 points banked into your '09 UY, your '09 UY hasn't even started yet so you still have until Mar 31, 2010 to use them. If they were Apr '07 pts banked into your Apr '08 UY, then they expire on Mar 31 of this year.
Banked points cannot be transferred. For example, if these were Apr 2008 points banked into your 2009 UY, they are not the same as Apr 2009 UY points. The Apr '09 points can be banked into your 2010 UY (subject to the banking deadlines) while the "Apr '08 points banked into your 2009 UY" cannot be banked again and cannot be transferred. They retain their status as "banked points" even after the start of the UY into which they were banked.
I'm not familiar with trading out so I don't know if you can deposit those points into RCI. Your other option would be to offer them for rent, in other words, offer to make a reservation for someone using those banked points. The risk there is that if they are Apr '07 pts banked into your 2008 UY, then they do expire on Mar 31, 2009 so availability will be an issue since you could only book something for Feb or Mar '09. You would also want to get full payment from the renter as soon as the reservation is made.
