Tried it, and like you, I was new. I do not recommend it. That swap is in the advanced category. Drive the truck first, a lot. Use it for what you want to use it for (within reason), and make notes on what you'd change and see if you can work around it with what you currently have. This will take months, in the mean time, start saving for mods. You'd be surprised how capable a stock truck is.
Short list to consider as first mods:
Budget lift and tires.
Some sort of traction aid (I.E. lunch box locker, if you search you'll find plenty on this site)
Make friends, listen and learn.
(I can only assume you're swapping this for an offroad truck, as there's no reason not to go with a V8 from the performance aspect)
But this is no way a beginners project. Trust me. It sucks that so many of us are going to be apprehensive to help, but I could write pages upon pages upon pages of what you'd need to do and how to do it. I really don't have the time to donate.
And just to be clear I'm not talking completely out of my rear end here, gaze upon these:
And yes, this was one of my first projects, and that IS a Jeep 4.0L.
I gave up on it, there is a 302 V8 in it currently. Which was challenging enough on it's own, and that's the easy swap.
