Looking for advice before I start my first resto

I have just purchased a non #'s matching 67 barracuda. frame is good. but everything else needs alot of attention. first thing I want to do is replace gas tank for the 383 and get her runnin. But what I want to know is, besides the obvious start of the motor, what brake system is recommended to replace the 4 drums and what suspension kit do I start saving up for? I figure for the price of the new kits, it's probably the way to go...unless?any advice to avoid common mistakes for first timers would be awesome TIA
