is the switch from fixed rendering pipeline to VBOs & shaders a big one in terms of performance? Also will it be hard to comprehend coming from doing only fixed rendering pipeline methods?

Not with your crappy code it wont. In general pushing triangles can be slightly faster if the driver is triangulating your quads anyway (likely), or slower if your card has hardware quad support and you're bandwidth limited.
Note that any benchmarking you do won't be worth squat unless you are aware of what bottlenecks you are running into.
