1999 Honda Civic Engine leaking, CEL P1381, P1337

I have a 1999 Civic EX that seems to be hurting right now, the car has 133k miles, the car has CEL with
P1337 (CAM Shaft Sensor) and P1381 (Sensor in the distrutor), Sometimes the engine misfire are very noticable, there is an engine and transmission oil leaks. The car has blue smoke from the exhaust under acceleration. As a result of all this the mpg is suffering and there is no power from the engine though this is wildly popular VTEC Honda engine.

I got the leaks checked out and there are three leaks supposedly, 1) Engine Oil Pan leak, 2) Cam Seal Leak (by the timing belt) and 3) Tranny leak at Axel Seal. So I started to think before I make the repairs that it might be all connected.

So I think the leaks are causing oil to get into engine and which causing the CEL. Though the leaks are not huge and I am losing alot of oil it cause of concern because of blue smoke. What should I do? Should I look at the leaks or the CEL? I know there can be multiple issue I really don't know what to get looked at first? Will I need the engine rebuilt because of piston or piston rings need to replaced?

Am I right to assume they are inter-connected? Any help will be greatly appreciated.

Thanks.
