Problems with 91 240 (key stuck/motor troubles)

[rocksteady_racer]

I have two problems.
Problem 1:
It's an automatic still and that little button on the automatic shifter broke off. So I tried to move it but it wouldn't budge even with pressing the pin down so I accidently snapped the lock on the shifter. Now my problem is I can't get my key out even when it's in park. I know my manual doesn't have the lock - is there any easy way to disable it so I can get my key out again.

Problem 2:
It's pretty cold up here in phila. Ever since it got cold my car started doing this weird thing where sometimes it runs really rich and won't start up easily without me kicking the gas the whole time. I was thinking maybe I got some gas with water in it or something and it's coming up now. All I know is that earlier today it was misfiring everytime I let off the gas. It worked fine after that for a little bit now it's doing the same start bit again though. I didn't have this problem until it got cold outside however it might just be that something broke because of the cold. My coolant temp sensor is pretty new so I don't think it's that.

Any help would be greatly appreciated because I have to get my car inspected soon. I also heard not to use fuel injector cleaner on the 91 240 because of the type of injectors (same with the max). Well thanks in advance.
