Hi Greasemonkey,
Even if your rating is current, I think before you embark on concentrated flying it'd be a good idea to pay for a few hours dual with a flight instructor.
Just go over the basics, some stall recovery, PFLs, basic IF (get out of cloud if you get into trouble), bit of basic NAV and some circuits. Most schools have a good idea of what to include in a refresher course, the flying club that I did my PPL with a few moons ago does a 3 hour course which is designed to get you refamiliar with a few procedures and gets your confidence up.
When that's done I reckon you'll feel much more confident and ready to embark on some serious solo hour building. Best of luck with it!
