Suggestions on performance upgrades for 225

Thank you, everyone, for taking the time to comment and make suggestions...it really helps. I've decided on the Clifford 225 combo package, which includes the intake manifold, headers, weber 2bbl DGAS 38/38 mm venturies, air cleaner and all the misc parts. I'm taking the suggestion of running a 2 into 1 exhaust with magnaflow or flowmaster (not sure yet).

So, the next thing I need to do is decide on a electronic ignition, upgraded spark plug wires, rotor/cap, etc. Can anyone point me in the right direction?
