Yes the 6.250" rod will work just fine. Yes there are plenty of shelf stock pistons available for this combo, both flat top and domed. Working around a 9" deck, you would need a 1.010" CD. Just so happens to be the same, within .010", as an engine with a 4" stroke and a 6" rod. So you can find plenty of pistons for this combo. You can simply juggle your deck height to make up the extra .010" in CD.
I personally like the 377 combo, and you are definitely heading in the right direction.
The best book grind cam that I could recommend for your application would be Crower's 00430 if the track you race at is a little slow in the corners. I'd recommend Crower's 00431 for a track with faster corners.
Engine RPM should be kept around 7,800-8,000 max with steel valves. You can run it at 7,800 all day long with good valve springs, and valve train, with no problem. Either of the cam's above will run at this RPM.
Your main weakness in your combo will be the block. Keep an eye on it, and mag it every 15 races or so.
I would also trade in your Team-G for a 2925 Super Victor Edelbrock. The Super Victor is great , modern intake, and perfect for your application.
