Depending on the UY you are looking for, you may get 2009 points when buying from Disney. If you have a UY after April, you get the points for 2009 and 2010. Based on posts on disboards, it sound like you get the 2009 points without paying annual dues for them. The 2010 points will have prorated annual dues from the date that you close.
If you receive 2009 points, I believe they will let you bank the points into 2010 if need be.
Also, if you have a vacation date in mind, when purchasing direct from Disney, your guide may be able to spread a little pixie dust and help you find accommodations even if others are reporting the resort is booked. (The resorts most likely that they can find availability will be the ones that are not sold out...AKV, BLT, SSR/THV, and GCV because Disney still owns a large portion of points in these resorts). There's no guarantee on this, but many have reported success with this, including DW and I.
