I would consider a strongly OOP based VFP framework like Mere Mortals, VFE, VPM or something. If you are doing SQL Server take a look at DataClass. This will provide you with a well designed set of abstract classes and services that you can build you application with.

Also, you should consider some OOP training like the VFP Boot Camp by Drew Speedie or Take Note training or Mere Mortals training.

Are you doing physical n-tier or just logical? Are you using VFP for all tiers?
