Just built this today. I based it off the plans from Ana White located here: http://ana-white.com/2012/03/plans/kentwood-bookshelf. I scaled it up to about 72"x36". I used a brad nailer and wood glue for the top and back planking, everything else was pocket-hole joinery. I still need to sand and stain it.
I've been able to get flush/smooth plugs by trimming them, using a fine tooth flush cut razor saw---
and sanding was minimal.
This little tool is very handy, for the small tasks.
The blade folds nicely into the handle.
Found it at Rocklers, for about $10

I actually used plugs in all the pocket holes along the front edges. It's a lot of work sanding them all down. And the plugs I got don't really blend in to well.
