3.0 to 3.4 swap questions (exaust, wiring, ecm)

Hi kinda of a newbie here. I have a 93 4runner with 3.0 162k 4x4 manual trans blown head gasket and knock. I found a donor 97 4runner good motor was in front end accident 133k 2wd auto trans. The radiator and condenser smashed in along with fenders and hood. I can get the entire donor vehicle for $600, so...
should I get it for the swap?
do I need to find an ecm for the 3.4 with a manual trans 4x4 or can I use the one from the donor?
I'm not worried about smog tests etc do I need to extensively modify the exaust, or can it cross over under the body?
can I use the 3.4 ac compressor or any of the lines
I have read posts about wiring here and there, but any tips/pics would be greatly appreciated.
