so it seems you have two problems:
- wrong access permissions for parallel port
- some timing issues when scanning

For the first problem, there should be countless suggestions around.
Maybe tweaking the right udev rule will do the trick. Or simply 
assigning you user to group "lp"...

The second problem could be more tricky:
Try 
export SANE_DEBUG_PLUSTEK_PP=10
then start 
xsane

and show us the output.
