New Homeowner: Do I have a bad ignitor?

After a few hours of running back and forth between the furnace, the garage (to get tools), and the computer (to get information and diagrams) I have come to the conclusion that I need to buy a new ignitor for our furnace. We bought our first house back in April, and this is our first winter here. It is also my first foray in HVAC maintenance, so I took some pictures. I'm hoping that some of you fine experts can either confirm my diag, or help me figure out the real issue if I'm wrong. _Furnace Info _Model: Nordyne Intertherm M3RL060A BWT _What I've Done_ I opened the furnace cover and right away I noticed all the corrosion. It appears that I have a moisture leak from the black assembly above the deck (the motor maybe??). I'd like advice on that leak as well, but for now I just need to at least get the furnace generating some heat. Right now the inside of our house is around 45*F.
