hi seb glad your liking your new toy......service wise i would just change the oil every 6000 miles and carry out the normal checks,to be honest i get mine serviced at the main dealer, no cambelt got a chain, plugs are supposed to be good for 100,000 miles but as mine has only 17000 dont know about that, the slight throttle delay can be fixed by fitting a sprint booster, just search ebay about £185, I leave the spoiler in the automatic mode to go up and down depending on speed so dont use the switch, and i think magnaflow do a rear box for the crossfire.....enjoy....chris
