Let's start a list:
A lot of this I'm just hypothesising as I have no first hand experience with these kind of mods. I'll update as people come up with stuff.
Port and Polish
Pro: Increased flow, more efficient combustion. Smooth power delivery?
Con: Expensive to get done properly, labour intensive. No adverse effect on drivablity? May have issues with TVIS.
Raising Compression
Pro: Higher compression ratio, more power from teh stroke.
Con: Increased stresses on reciprocating parts (in the long term)? Tendancy to ping?
Aftermarket Cams
Pro: Better breathing, bigger intake charge, more power.
Con: Sacrifice idle quality, increase fuel consumption, powerband moved upwards and low RPM power lost?, standard ECU may be unable to cope. Daily driving may become a pain in the ass.
Advancing base timing
Pro: Ignition earlier on the combustion stroke, more power across the rev range.
Con: harder to start on cold mornings, tendancy to ping, may confuse standard ECU.
Aftermarket ECU
Pro: Much more flexibility than standard ECU. Ability to retune after adding mods, possibility to have separate maps for daily driving or max power, ability to add aftermarket components that the factory ECU may not be able to run (eg. larger injectors, coil pack ignition).
Con: Normally would have to sacrifice things like idle speed control, ability to drive other components such as A.C, Cruise etc. In the relatively simple / oldskool ST162 probably not such a big deal. Mostly illegal unless engineered / emissions tested... but so are most modifications. 
Intake / Exhaust
Everyone's been there and done that.
Knife edging crankshaft / lighter flywheel
Pro: lighter reciprocating mass = freer spinning engine = higher revs = higher peak power. 10 000 RPM also = porn.
Cons: rediculously expensive, torque is sacrificed.
I'm pretty brain dead atm, but might also be worth thinking about upgrading valves / valve springs, injectors, ignition (plugs, leads, dizzy / coil / coil pack) systems, full balance / blue-printing and so on and so on.
