Options and Opinions

[husker boxster]

Thanks to the link Bmussatti provided in my other thread, I've spent last night and this morning going through the nation's entire inventory of new and used Boxsters. Have run across some enticing possibilities. However, I am unsure of some of the options listed (my 01S is relatively naked), so I was hoping for some insight. Also have a few questions. Here goes:

482-TPMS ?

475-PASM I see PSM and traction control are std on 06 & 07 but what is the difference between PSM and PASM?

PPA & PPB These are listed as Preferred Pkgs, but what do you get with them?

639-Sport Chrono w/o PCM What is PCM? And what do you normally get with the SC option beside a big clock in the middle of your dash?

Other than 15 addl HP, is there anything different with the 3.4 engine vs the 3.2? Are the same design flaws built into the 3.4 (RMS, etc)?

My original plan was to buy an 05S next July when my house is paid off. Then the 06S in NOLA showed up and I figured I could swing it. Now 07s are starting to creep in. Maybe someone better get me to an intervention.
