Also is it worth upgrading to Iridium spark plugs + new blaster coils (MSD) and new ignition wires ?

No, don't get iridium. Opt for the BRISK Silver plugs instead. I also wouldn't worry about upgrading the ignition, especially without other major upgrades such as camshaft and head work.

Yes, but you'll need some connector adapter... the connectors are different between the S and Non-S.
