USDM 96 Celica ST Engine swap to 3S-GTE Gen3 HELP, need help deciding what to do Options

[KADE]

I like everyone else on this forum love the celica and like most of you, I want more out of what the stock motor can offer (without throwing lots of cash at it)
What I have is a Cherry Red 1996 Celica Liftback 2.2L w/5-speed transmission with 220,000 miles on it, a few months ago the engine started to finally show signs that it was ready for the ol scrapyard.
Given that I have grown attached to the car and I DEFINITELY NEVER want to give it up i decided that I would like to take this opportunity to put the 3S-GTE GenIII motor into it in place of the stock engine (5S-FE i believe)
I opted for the Gen3 motor because it already comes water cooled (based on a couple months research) and comes right out of the same chasis frame as my vehicle AT200 / ST205.... (if theres a difference between the two please correct me.)
now here's where my mechanical ignorance kicks in, I'm not in anyway a mechanic nor am I experienced in that field and I'm hoping that some of you more experienced mech's can help me make the right decision(s)
I have lucked out and gotten a decent deal on a set of parts as listed

Parts I currently have

3S-GTE (complete motor, CUT wiring harness )
Front Mounted Intercooler
Engine mounts
E-153 tranny + LSD (ALready connected to the motor with Clutch, Flywheel etc...)
GT-4 Axles (I Just recently discovered do NOT mount up to the E-153 LSD transmission)
ECU

The things I don't currently have but I do intend on adding before the swap starts

Walboro 400lph fuel pump
Act 6 puck Racing/Street Clutch kit with 300 lb/ft torque sealing
3" Exhaust + Flowmaster Delta 40 mmuffler
GT Shift Cables (I read up and they are needed for this swap to work)
ST205 rear transmission mount bracket
Booste Gauge (Aftermarket)
MR-2/Camry Axle

Now heres where things get confusing for me, I'm not the one who is doing the swap but I am paying a professional mechanic to do it so I want to make sure that he has EVERYTHING needed and that there wont be any SURPRISES!!!
I have been researching a lot over the months and I know people prefer the front clip style swap but I didn't have that available especially not for the deal I got. I know a lot of people will frown upon doing things this way but I do ask for your patience and any and all HELPFUL and encouraging advice some of you who have undergone this may have.
If there are any parts needed that I did not have listed or I CAN'T remove from my stock motor please let me know.

if you have a GT with a 2.2 5S-FE then you do not have an AT200, you have an ST204. your title says you have an ST which is an ST200 but it comes with a 1.8L 7A-FE. what does the number on your firewall say or post a pic of your engine

yes the stock radiator will work on your 3S swap.

all your questions have been answered several times in the stickys. read them again and again.
