The fork oil is a very specific job needing a manual and a special tool, I don't want to insult anyones mechanical knowledge but if you have never done it before, best to take somewhere else. Engine oil on the other hand is easy, the drain tube to any softail is on the right side by where the frame meets the swing arm, has somekind of plug in it. Start and run bike for a little while, long enough to get it warm but not hot. Remove fill plug and then remove plug in drain line. Using a peice of cardboard or something put in between filter and frame , directing the oil to your drain pan instead of where ever it goes. Put 1 qt oil back in (after everything is reinstalled) start the bike and make sure the oil light goes out, when it does shut bike off and fill to the point that when it is standing upright you get a little oil on the tip of your finger, over filling may result in loss of oil cap from pressure (been there)
