If you're going to rebuild, definately at least throw some high-comp pistons in. It's probably the most crucial component of having a "fun" N/A car to drive. I wish there was some magic list that i could put out - a=blahHP, b=blahHP, c=blahHP - but it doesn't work like that. It works more like a+b+c=blahHP. Lets say if you were to get 12.5:1 pistons with stronger rods($1000), some street cams($400), intake($50-$100), TB ported($100?), header($200-400), catback($400)....you would have alot more power. Maybe somewhere around 180-190hp. No matter what mods you have - if you get a UDP($160) you'll get a bit more power to the road(maybe 10hp). If you get an S-AFC($350) and some cam gears and dyno time($250 for the gears, $80hr for dyno time) then you could tune it to run even better. 200-220hp isn't impossible from the 420a, 250hp is the upper limits of what you'll get with a full out race setup(headwork, valves, ignition, etc).
