First up, don't get overwhelmed. Don't think EVERYTHING has to be fixed immediately. This will lead to frustration. Getting it up in the air is a good start. Make a list with your buddy.
1. What does it need to run?
2. What does it need to be safe?
3. What does it need to stop leaking?
4. What does it need to be nice?
Take care of #1 and #2 at the same time. Get it running, go through the brakes/lines/suspension/steering. You don't have to do it all at once. Pick small jobs. Front brakes. Brake hoses. Spark plugs. Wires. Points. Carb. Etc etc. Just keep at it. Leaks are no big deal on an old car. Just make sure the oil in the trans and engine stays full. However, once you have 1 and 2 done, your leaks will probably be pretty easy to deal with. The trans only leaks from a few spots, and same with the engine. Find the leak source, and you'll be able to understand how to deal with it. Most you can take care of in your driveway.
With each thing you check off the list, you'll be that much closer to meeting your end goal.
