that would be a pretty big document. IMHO, the best way to figure this one out is just to research different systems. if you want to go all grain, you are definitely going to at least need a MLT and depending on your DIY level, converting a plastic cooler of some sort is one of the easier ways to go about this. there are many threads on building a MLT from such coolers, this is one of the more popular ones:

secondly, you will need a large vessel for the hot water and/or boiling the wort. you can conceivably use the same vessel for both functions, but it's more convenient with two. again, there are many threads dealing with the conversion of kegs into HLTs and BKs, but bobby, as you mentioned, has great videos dealing with this conversion.
lastly, you will need some sort of stand for brewing on and a way to heat the water and boil the wort, and your imagination is the only limitation here. a turkey fryer is an easy way to accomplish the heating. you only need one burner, but again, two is more convenient. the stand could be wood (as i use), metal (which is more time consuming and expensive to build), pre made structures, chairs, tables, anything that will put gravity on your side.
i have a wooden stand with two kegs (HLT, BK) and the old cooler MLT. my beers turn out great with single infusions (no HERMS or RIMS), i have a pump, but i am anal about amounts, so I often measure strike water, runnings, and pre boil volume with graduated buckets. and none of it cost me all that much money to do (I found a welder to put in my valves/couplings for pretty cheap) and did the rest myself. again, i think you just need to search and examine as many systems as you can from here and in the meantime, start locating some thrifty deals on kegs, coolers, valves, etc.
