One point, you should try to bump start it gently. Some cars are known to break straps in the clutch cover. When I had my garage I built a few custom clutch covers for some die hard eoc guys who kept breaking straps. It will also wear the clutch out somewhat faster but clutches are a wear item anyway. If/when it does you just get kevlar facings and it will easily outlive the car.
Also be aware that EOC can have a significant impact on cat life because of the constant temp cycling. Most OE cats are good quality and shouldn't go bad too fast. The whitebox specials (high flow, el-cheapo ones) not so much. They're ceramic core and not always top quality. I changed the cat on my subaru for a stainless core one. On a restart (engine off for about a minute) it lights off in about 10 seconds versus 40 for the ceramic core one but while running doesn't really improve overall emissions...
