i would back the compression ratio you want down to 9.5:1, not enough difference in power output to bother with, but it is less detonation prone so you can use a lower octane fuel.
the 32/36 weber is a good choice, just remember to run a regulator set at about 3.5 psi.
the HEI is ok, be prepared though to replace the module with a stock ac delco module, the aftermarket modules are hit or miss on durability. and remember to use the proper grease when replacing the module. in fact you might take the supplied module out, and clean the module and mounting surfaces thoroughly, and use some good grease to help the durability of the module in question.
as for the high ratio rocker arms, i think i would go with a cam change instead. high ratio rockers are a nice tuning feature, but if you get the cam right first, and find that you still need a little more, then consider the high ratio rockers.. the nice thing about going this route is that you can use the high ratio rockers on just the exhaust if you decide that you just need a bit more from the exhaust, for instance.
i would also install a header and a good exhaust system, as that will give you the proper out flow as well making for a smoother over all run for the air.
