1986 Coupe GT in Baltimore...need advice

[vze2tnyf at verizon.net]

Just bought an '86 Coupe GT and love it when its running "right."  That being said, I'm looking for help with;
 - A good mechanic/shop in the city of Baltimore, MD
 - Help with a cold start problem (car is hard to start and runs rough for a minute or two before warming)
 - Engine, when warm, sometimes run's rough.  Won't rev freely and clean, power delivery seems to have "bumps" in it.  You can hear faint hiccups in the exhaust note.  This happens accross the rev range...but doesn't happen all the time.  Seems kind of like a bad tank of gas (I did notice this for the first time after filling up a week or two ago with regular grade at a Mobil.  I have driven the car down to 1/2 tank and then filled with high test at different gas station.  I assume that its a fuel or fuel-system related problem but don't know for sure.
 - There are some other items but I don't want to write a book here so I'll stop for now.
Looking forward to some good advice, thanks in advance.
