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.

actually you dont. the ST cables are slightly longer than the GT, so if you get an E153 trans then you will be just fine. now that we know you have an ST you do have some options.

have you already got the 3S-GTE? is your heart set on a 3S? what is your budget? there is another engine option that will be just as easy to install and half the cost of a 3S.
