Questions about reinstall for resale

I have a 2008 MacBook that I want to sell possibly to a friend (and if that falls through, eBay). I reinstalled using the disk but then it wants me to create a user account and register which I don't want to do. The only reason I didn't just stop after reinstall is that I want to put back photoshop and Aperture on there for this person. I won't be using them anymore so I don't mind giving it to them. Is there a way to bypass the new user account and just put these programs on? Or can I just create a generic username for now? They can change this info and password later? The only thing I saw was that they can not change the folder name so I just put MyMac on there. If I just do the reinstall and quit before the create a new user page, can the buyer download the programs I've already purchased and supply them with the registration codes?? I don't have the disks because I downloaded the programs.

Thanks for any help from a very unknowledgable Mac user!!

 

The programs are legit and I have purchased them. The friend I'm selling to (well a friend of a friend, I don't know them that well) wants these 2 programs and is willing to pay extra for them. If I end up selling on eBay, I can just reinstall again and quit before that movie starts so the new user starts with a fresh computer?? If I sell it on eBay I won't include the programs then. I just didn't want to sell the computer for extra to this friend telling him I can give him those 2 programs if in fact I or he can't get them back on there. Will the serial numbers work again? I wanted to install myself just to be sure they worked ok.

Thanks
