1st it could be alot of things with your air injection relay, pump, could have a vacuum hose loose not allowing the switch over valve to activate the air injection valvesyou need to have a activations test done at the dealer. you may even have a bad o2 sensor not droping below 40 mv.

second you have whats called a rev limiter on your car i call it STUPID PROTECTION. its in place to stop STUPID PEOPLE from over reving there car in park or neutral. this is normal you paid for this option.

thirs it sounds like you need a ac blower speed regulator i just happen to see one on e bay a few hours ago the part number is 140 821 84 51.

dont worry about losing anything when your battery is disconnected(maybe throttle position just leave key on for about 5 min. after reinstalling battery) oh any you will need to reprogram your windows one touch feature but not a big deal.
