Default 1995 Camaro LS3 Swap HELP

Hi guys, I'm new here so I'm not sure if I'm even doing this right.
Does anyone have of could anyone get me a list of parts I will need (aside from engine and trans) that I will need to swap a 3.8 V6 out of a 1995 Camaro for an LS3?
I have an LS3 & T-56 Magnum trans for the car, I am unsure what k member and or wiring harness to use for the car, as well as tips for suspension and braking components to make the car handle greatly around turns. Any help would be appreciated.
(Looking for tubular components for weight savings and increased stiffness over stock stamped parts)

I'm in the same process, but with a 1993 Z28.
I bought a UMI K-member and upper and lower A-arms. I'm going with LS1 poweder coated calipers and rotors at this time, but the C5 is a better up grade. I've Read about the ATS calipers and gen 5 or 6 Camaro rotors working well.
Want to increase stiffness get subframe connectors. I bought UMI 3 point subframe connectors. Look at Koni shocks too. I bought coilover, because I will race my car sometimes.
I'm going to go with either BPharness or Speartech for the harness and there's PSI Conversion.
BPharness is a good price with great quality, but a long time to get made.
Speartach has a premium price and do great work.
PSI Conversion I have no experience, but the prices look good and they have a good reputation.
You will have to up grade your fuel pump.
Lingenfelter TRG-002 58x-24x crank sensor trigger is needed.
LS1 PCM for the computer and bracket.
LS1 accessories, BUT heard you can put the 5th Gen accessories and LS3 in a 4th gen.
You will need a different throttle body that will accept a cable for the gas paddle and not drive by wire.
LS1 headers and exhaust.
Tune.
That's just off the top of my head.

So LS1 parts, for the most part are interchangeable? I'm looking to race this car at the track for autocross so can you tell me, those k member and upper and lower control arms are those tubular units? What rear end are you gonna run? I'd like to go independent rear

APP sensor (gas pedal) if drive by wire, ECM and entire harness ( all 3 preferably from same vehicle as engine), modified or aftermarket standalone harness, all correct sensors to match ecm and an ecm tune. Are you deleting VVT/DOD/AFM? Surely you are if this is to be a performance engine. Thus lots more parts. Lots and lots of homework if this is a first swap. lots and lots of money too. Depending on trans type some means of providing VSS, Fan(s) controls,on and on and on. The first swap can be a real learning experience. Hundreds of hours of research first then hundreds and hundreds of dollars for parts. Adapters required, mounts fabricated...............This is with no engine mods which would seem futile if it is to be in a race car.
Just one opinion here of course.

Some LS parts are interchangeable.
Go on the UMI and look up what you want and yes, they are tubular.
My rear end is a Strang 12bolt rear end and I'm going MWC 9ich. I drag race.
Google "Heidts IRS" and you will find what you need for your IRS.

I would treat this as an old car swap. Why bother installing LS parts on a car that never had a LS in it? Does a 95 even have a BCM? I bet not. Are the gauges CAN? I bet not. So treat it like a 1970 Camaro...

I would get a Holley Terminator X Max EFI system, and proceed accordingly. Holley also makes hard parts to mount the engine:
