New to LS swap and need some buying advise

Got a clean 85 chevy truck and looking to buy motor mounts and all fuel components and any thing else i will need to do it as quick as possible without waiting for parts.
I bought an 03 5.3 with a 4l60E. I need links please to the easiest motor mounts to buy, i know dirty dingo has a few different kinds for the 85 trucks i believe. I got an electric fan coming for cooling because i dont like the clutch type. I want to do an inline fuel pump but havent read many threads on how to plumb the lines into the existing fuel rails.
I been reading on a few sites for a while but i really need a good list of items needed besides wiring harness and ECM flash.
Any body know if I will need to alter the drive shaft? It had a 305 turbo 350 in it. Can i use the 4l60e mount and possibly move the original cross member ?
I want to use the original gas tank if i can. Please help i need some solid advise before i pull the trigger on purchases . PLease give me specific items that will make this as smooth as possible.

Help me please!!!!!!

Honestly, I don't know a thing about doing a swap into your body style or swapping into a carb vehicle. I would email dirty dingo and ask your tranny mount questions. No clue about using an inline high pressure pump. If it were me, I would measure your current fuel tank and head for the junk yard to look for an injected tank that you could swap in there with a walbo 255.I personally have had poor luck in a carbed application using an inline pump.

As far as fuel goes, You can use an inline pump but you need a standard fuel pressure regulator or possibly a rising rate fuel pressure regulator and a return style system back to the tank.
