Hey Alan, you may want to do is give it a quick wipe down with either a water dampened cloth, or a cloth dampened with Gum turpentine.
This should show up any remaining glue spots that you won't see until you start staining.
It may also raise some of the softer fibres (Depending on the body wood) which you can then knock back with some 240 or 320 grit.

You wouldn't want to go much further than 320 (or some use 400) grit paper else you run the risk of the stain not keying in due to the smoothness you've created.
If you don't see any shiny glue spots, and if you can't feel any "Fuzz" after the wipe down, or there is no evidence of machine marks then you should be good to go.
