The oil leak is right around
(http://i54.tinypic.com/15zq53.jpg)
Hard fix?
What needs to be replaced to fix this?

I'm guessing I need one of these,

That would be your front crankshaft seal in most cases but there are a few gaskets around that area as well. If your going to replace the timing cover gaskets replace the crank seal as well.
Not a hard fix.
1. Remove drive belt and crankshaft pulley.
2. Then lock the crank at TDC using the flywheel or an 8mm drill bit, loosen the crank bolt and remove the crankshaft hub that sits behind the pulley. Once this is off you will see a round seal that sits in the lower timing cover.
3. Use a seal puller or screwdriver and carefully remove it. Clean the inner surface of the timing cover where the seal was.
4. Apply some oil or CRC to the outer diameter of the new seal and guide the seal in carefully. You can use a socket and hammer to gently tap the seal into place. Guide it in until the seal is flush with timing cover surface. Take note of this before removing the seal. Also the seal has a unique spring around the inside of the seal to help it seal against the walls of both the timing cover and the crank hub. That's why it is important to ensure you are careful when fitting it.
5. Then refit your crank hub and use a new crankshaft bolt (recommended). With the crank locked in place tighten the the hub with the new bolt. (Make sure it is tight).
6. Refit crankshaft pulley and drive belt.

Nevermind the oil leak, look at those ITB's!!! Wait are those carbs?!
That kit you linked would be a good place to start. I would also replace the gaskets that you have to remove in order to get to that section. Profile gasket looks like one of them for sure...you may want to replace your water pump since you're going to remove it anyway...
Nick above has pretty much nailed it with the instructions though!

My dad told me I should pick up some gasket sealer before I do anything, will this work?
Nick so I won't even have to take off the timing chain cover?
-
No, if only replacing the crank seal then don't remove the timing covers.
-
It is probably just the crank oil seal. If it is just take of the pulleys and use a small pick to remove the seal. You do not need to order one online. You can get on at Motion Industries. They have stores in most cities. Their seals are also a better quality.

Awesome guys thanks guys!
I'll try and get it done tomorrow.

So is this what I need?

Read the thread and I am wondering did the front seal stop the oil leak?
