it should be easy for you seeing as you're mechanically inclined enough to do those other things. First off wait till the engine is cold so pretty much all the oil is in the pan and so you can remove the header. Second jack up the car as high as you can (safely) and drain all your oil, leave it draining for a few min so you get most of the oil out of the pan. Third, remove the oil filter and oil pan bolts which i believe are 8 or 10mm bolts if im not mistaken. Your oil pan is now removed, when you install the new one make sure you have a new oil pan gasket. Apply sealer around the rim of the new oil pan so it has no chance of leaking any time soon and place the gasket one it, then hand tighten all the bolts then go around with your ratchet and tighten the bolts CRISS CROSS so it seals perfect. Finally throw the oil filter and drain plug on and add the oil.... done.
