Going into my 4.6 soon

I plan on getting into my 4.6 pretty soon, runs perfect though. No oil is leaking or burning. I'm going to add "PI" heads and intake, upper plenium, cold air, throttle body and headers. Should I go ahead and pull the whole block out and have it cleaned and replace the stock componets w/new? I feel I should add forged pistons also 'cause have future plans (1 yr. or so)of adding roots style supercharger, or should I just leave the bottom-end alone despite having 101,000 miles of no problems on it? Which headers should I go with '96-'98 or '99 up? I'm pretty sure '99 and up due to "PI" heads, but not certain, and what throttle body size, want to run BBK but not sure on size. I found a forged pistons rebuild kit in Summit for a little under $800.00, and pulling the block and replacing the bottom-end could seriously be felt on my budget and extended garage time( even with help of friends) any replys will be appreciated. Oh yeah, has anyone else ever broke into one of these mod motors? I hear it's rather time consuming and a head-ache.
