The first step before any engine repair is to wash the vehicle and clean the engine compartment/undercarriage. Do yourself a favor and spend $5 at the self service carwash cleaning all the crap off your engine before you put your clean hands and tools all over it. It will help prevent crap from falling inside the engine during disassembly/reassembly, but more importantly for you it will allow you to see exactly where the leaks are coming from.
Always always always spray the engine clean to find the oil leak, it will be the greatest investment of centerconsole quarters you ever made. I would remove the two plastic covers under the engine compartment, they have 10mm bolts that hold them to the bumper, fender and crossmember. Take a peak underneath and have a plan of what you are going to clean.
Leave the engine running anytime you wash it, otherwise you may have trouble getting it started again. It is okay to use the high pressure water just be careful, DO NOT directly spray the distributor, electrical devices, electrical connections, gaskets (such as the oilpan or valvecover gasket), and vacuum lines(including the TB) with high pressure water. Feel free to use any low pressure spray or soap but avoid getting liquids into your spark plug tubes(they dont work well wet
).
Thats pretty much it, get it squeeky clean so you can find the exact location of the leak and so that you are ready to rebuild a clean engine not a grimey one.
