I have several questions, but I'm going to have a story around the questions. I would REALLLY REALLY appreciate any help/answers to the questions. THANKS!

Recently my parents told me they wanted to sell their 1976 911s Targa. They've had the car since I was about 12 and I've always loved the car, but rarely got to drive it. They put it on the market and didn't get what they wanted, so for relatively little effort, I was able to get them to "give" me the car....
I'm very excited, but without a doubt, it's going to be a money pit for me, I'm ok with that though. I'll just upgrade it as I have time.

So first things first, I'm going bring it to my home from their home this weekend. I am planning on towing it with my jeep and a car dolly. Is this going to be ok? Just put it in neutral and tow it?
I should talk about the condition of it. It has 2.7 with 140,000 ish miles on it and has not been rebuilt. It leaks oil like crazy, but only happened in the last few thousand miles. (Still sounds/drives amazing when it's running). Up until that point it was being driven fairly regularly. There are many spots it's leaking. I replaced the lower valve covers gaskets (? under the engine that I could easily reach) last time I was at their house, and put a new hose on one area that I saw leakage, but this did minimal to help the leaks. It is also leaking from the top of the engine, which is where I think most of the oil is coming from. Body is in OK shape, little rust, but nothing affecting the shape. My dad had issues with the shifting a few years ago and replaced the plastic piece that was causing problems and it shifts perfect now. I have the AC and heater components but they are not installed. the heat exchangers on the bottom need replaced as they are pretty rusted. the Fuel line needs replaced in at least one spot, maybe more.
After I bring it home I'm assuming I need to find a mechanic/someone with knowledge that can help me. My goal is to spend just what I need to spend to get it running well. I could probably be convinced to do some upgrades along the way, but I want to just get it running safely. I don't have a ton of money to dump into it at once, but I could afford as much as 5K to get the engine going so I can enjoy it some. I'm not sure if I want to do the work myself or pay someone to do it. Eventually I see myself getting it repainted, putting a new suspension on it, new interior, etc, but again, just want it running somewhat reliable so I can enjoy it now too.
I should note that I am somewhat mechanically inclined, I have done brakes, spark plugs, fuel pumps, alternators, AC compressors, etc, but never taken an engine apart. I'm a Jeep guy but am getting into this porsche thing also. I'd like to have a car that I can go crazy fast in as well as a jeep to crawl over anything in.

SO IN SUMMARY:
Questions...
(1) Can I pull it on a car dolly safely in neutral with front wheels on dolly?
(2) Does anyone know a mechanic/knowledgeable person to talk to about this car near Newark Delaware(live here)/Aberdeen Maryland (work here)/Philadelphia area (close to here)???
(3) Can I get it running somewhat reliably without having to sell my house?! and then get it into much nicer condition over the next several years?

Thanks! If you're in my area and have knowledge and want a few free beers while we chat about it please contact me!
