Since you have people there that told you specifically to replace those parts, The guess is they know those parts were damaged.
There is a bunch of YouTube videos that walk you through what to do. Personally I prefer a Chiltons repair manual- and having that book in the truck at all times is a major help to new mechanics.
There are usually shops that specialize in alignments, which yours will need after this is done. Get those parts replaced and take the truck into one. When they inspect it if there is other parts damaged or worn they will specify which need to go. You can pay them or diy, then return the truck afterwards for the alignment.
You will need a few specialty tools for this, like a pitman arm puller. Most people only use it a couple times so buying one isn’t best choice. Auto parts stores like Orilleys and Autozone have a “loan” program where they sell you the tool, you use it, then return it for your money back. You need to check with your local stores as to what tools they offer.
I suggest starting off with only the basic stuff required until you get the truck useable.
Definitely tackle only one task at a time. Having multiple things torn apart at once is not a good way to learn mechanics. Doing all the front end first, then get into engine and save fuel tank for last.
Phone cameras are helpful-take detailed pictures of each item before disassembly. This
can help a lot when reassembling later. Speaking of pics- take a bunch of pics and post them here. There are a lot of knowledgeable people here that might see something worth while of mentioning.
The front end components make since with the crash. Definitely the post above is the better long term fix than another mostly worn out one from another truck. The only reason to do that is if you are totally broke and plan to do the work again in another year or so when more cash is on hand.
The distributor needing replacement is confusing.
fill out your signature line with both truck details, engine, trans, etc. look at the others examples inntheir posts (mine is not a good example) Specify which truck is the parts truck, and remember it could become a source for a little income if others here are looking for a part on it you don’t need. So include body pics if not all rusted out and interior pics. Show pics of theexternal fuel tank will help with that task, and fuel pump details.
