Must I wash with DAP if I've already sanded the walls?

I removed the wallpaper, washed and scraped down the walls, shellacked any ripped paper on the drywall, filled holes with lightweight spackle, skim coated part of it with joint compound and then sanded the entire thing (the walls were in terrible shape).

Must I now wash with TSP as well or can I prime straight away? I'll be using Olympic no-VOC interior latex primer.

Please please please tell me I can go straight to priming!

I would use PVA primmer on bare drywall.

Thanks for your reply, Jack.

There isn't actually any bare drywall. There are two layers of paint on most of the walls, some patches where one layer has come off, shellacked patches where the paint and the drywall paper came off, and areas of drywall compound. I think I need to be primarily worried about residual wallpaper glue and having the paint stick to the old paint, don't I?
