To be honest you car looks better then mine when I got it... Now its time to get wrenching. A large majority of repairs on a 2002 can be done by a beginner and there are a lot of knowledgeable folks on this forum that will help out as long as you provide in depth details about the problem... Pics help out a lot too.
Here is a link to the transmission shifter mount bushings mentioned earlier. pretty easy but messy job.
Just noticed that the link below incorrectly say 1 per car! You will need 2.

For the oil issue I would start with an oil change and try running 20W 50 oil and use a good mahle brand oil filter. In the meantime I would either reconnect the oil breather or place the hose into a catch can to collect the vaporized oil and get a feel for how much is actually coming out.
Here is a post mentioning a similar problem:
