Which of the magsafe chargers are ok for the 2011 MBP 13?

For normal charging you will want to get either the 60 watt or 85 watt MagSafe Power Adapters. Either will be able to supply enough power for your Mac and charge the battery. Using the 45 watt adapter will not damage your MBP but it will be unlikely to supply enough power to charge your Mac.
The Apple MagSafe Airline Adapter (cigarette lighter-like one) is specific to DC power ports available on some airlines. It will not fit-in or work-in an automative cigarette lighter port. This adapter only supplies enough power to operate a MBP/MBA/MB but not enough to charge any of these Mac's batteries.

It will simply charge faster, nothing else. It won't damage the battery in any way.
Not really.... the power logic circuit on all MBPs only allow charging at a certain rate. However using the 85w one will be less strain on it and not get as warm b/c of less demand.
which wattage comes with the 13" mbp? I could probably just reach over and unplug it and look, but i'm too lazy to do that!
60w

60. you can also use the 85w to charge, and it will charge just the same as if it were a 60w adaptor.
Any idea where I can get a car charger for a MBP 15"? If none are available, what voltage does the airline adaptor use? I could just chop the plug off the end and attach a car cigarette lighter plug.
First - Apple makes an airline adapter - Apple MagSafe Airline Adapter - that includes a cigar lighter plug for airlines that used it and Apple says it won't work with a car plug. Anecdotal evidence in other posts suggests it works with an Air, so unless there is some weird polarity issue it should at least provide power to the MBP; if it does it probably won't charge but will run the MBP.
Not sure about the airline plug voltage - I think it depends on the airline but most were around 15v DC. Your best bet is probably to buy a DC/AC inverter for the car and plug it into the power plug and the Magsafe into it. Depending on the current draw it may blow a car fuse; but I've used them to power PS2's and TVs in a van.
I've seen car adapters advertised for MB's and MBP's; but with one exception the prices were so low that it's clear the Magsafe is a knock-off. I personally wouldn't trust my expensive MBP to a cheap 30 buck adapter - if it fails wrong it could fry my MBP.
At least with an DC/AC inverter the Magsafe power supply acts as a go between so the worst is you won't get enough juice to charge.
You make a very good point about not wanting to use a dodgy adaptor on an expensive macbook. And I just checked the product description for the airline adaptor, you're right it will power the MBP but not charge it. Which sux because I dont want to use the macbook in the car, just charge it. I wonder if it will charge when the macbook is off but plugged in.
