You are going to have to remove the intake plenum to replace the fuel hoses.
As for the rest of the leaks,i would clean off the oil soaked areas with brake parts cleaner,[cheap about $1.50 a can] then look at the areas intermittently for the origination point source of the leak..Also,tighten any loose hose clamps around the other leaks...

you don't have to take off the throttle body. just undo all hoses and other junk connected to the plenum. i hope you have a service manual because there's a sequence and torque specs that you have to follow for your hex bolts. this isn't the best job to do if you're not an engine guy like you said in the other thread. but i'm sure you can do it. you're going to need a variety of tools to do the job. you need to kill the fuel pressure before you start doing this. and you'll leak a little coolant when you remove a few select hoses if you don't drain the system beforehand. you will need both the upper and lower plenum gaskets. good luck man. if you don't have a fsm, send me a pm.

in regarding to the fuel rail, make sure you get a BIG philip #3 so you could unscrew those mad tightened screws. I was a being bone headed when I did mine, I ended up slotting a few screws cuz I used size #2.

Dude like you asked me earlier and now I'm answering, YES as long as you have all the necessary replacement parts and you're at my house by 1pm CST Alex and I can def have it done by 7pm CST, if you want and can be here by then, give me a call.
We got all the necessary tools for the job and I actually still got about 1-2 ft worth of fuel injection hose which is the correct size you need as well as 1-2ft worth of vacuum hose to replace all your dry rotted existing vac hoses.
If you were to bring you car over, you wouldn't have to do anything but clean the parts we removed and have em ready by the time we're to put everything back together. You'll get a decent/reasonable labor charge
In fact if we finish early (depending on how much you wanna clean) we can all go out for ice cream

assuming that you had all the parts there with you and a garage to work in, then it'll take around 12hours or less.

I would have to agree, took me about lil less than 12 hours when I did my valve cover gaskets and some other gaskets and replace all the hoses but I did injectors/gaskets on my g/fs recently and I took about 2-3 hours not counting getting a part we needed.
