Not sure from what you say why you changed oil pump. In any case if you changed the seal and it is still leaking maybe you damaged it on installation? The timing cover gasket should be changed if it is leaking. As far as oil pan/oil chamber you might get by just tightening the pan bolts otherwise a new pan gasket is in order. I would get a Haynes Auto Repair manual for your car. Most Auto supply stores have them.
