From memory you would need:
Front cover gasket kit (which should include the front crankshaft seal and an oil pump o-ring)
Oil pan gasket
Valve cover gasket kit (should include the grommets for the valve cover bolts)
Upper and lower intake manifold gasket kit.
EGR valve gasket
There are also various seals you'll get into for the right side driveaxle going into the PTU and the transmission you might think about changing out. I believe there is one where the driveaxle enters the PTU and one where the PTU enters the transmission. There is also a seal where the rear driveshaft enters the rear of the PTU.
If you haven't done it in a while it would also be a good opportunity to change out the PCV valve and the spark plugs.
All that being said, this will be a very time consuming project for you - one I personally would not embark on for a 300k engine. Having just pulled the motor on my 2003 3.0 AWD I know it is a major task. This is the 4th motor I've ever pulled and was by far the worst, mainly due to the AWD, transverse engine and tight spaces. I bet it took 4x longer than any of the others. My advice would either be to live with the leaks until the engine finally goes bad (which can't be that much longer with those miles on it) or to find a low mile salvage motor to put in. JDM Mazda Tribute engines (with supposedly 55 to 60k miles) are out there for under $1000 shipped or you might be able to use a Duratec from other vehicles (Ford 500 etc?). I did a 03 Taurus/Sable Duratec swap into my 03 so I had to move some parts over from my old engine which wasn't too bad.
One more thought - could your leak just be coming from the crankshaft seal on the front cover? I'd investigate that carefully and if so just do that seal with the motor in the car - that would be an ugly job too but the ugliness pales in comparison to pulling the motor.

Don't panic yet! I thought I had the gasket problem with my 2005 Duratec 30 V6 and I even suggested it to my mechanic who knows these engines extremely well. He said it is usually the crankshaft sensor o-ring that shrinks with age and leaks in the same area. I left it to him to do the troubleshooting. He is extremely honest and the complete repair including the sensor, engine cleaner and labor totaled less than $52.00. The engine has been completely dry for weeks!
