Yeah, most people seem to agree that there is no reason to make major changes to your lifting routine. Just so that you have a good productive routine before firing up the test. Let the test amplify the training effect.
Diet is pretty individual. 1.5-2+ g/lb bodyweight in protein is pretty uniformly recommended though. Calories are adjusted usually by trial and error based on how much weight you want to gain or lose. Things happen so fast on test initially, the learning process that goes along with diet/training also seems to progress much faster. I learned more in my last year of using ph/ps and test e than I did in maybe 5 years previous.
On a bulker, I tend to do best with a shit ton of protein, way over the recommended amount, and low to moderate cho and fat. Leads to relatively lean gains for me. If I really want to decrease total bodyweight, I had best stay the hell off of the roids. Makes it at least feasible for me.
