2000 ford escort zx2

[CarDumb]

Okay it seems everytime i turn around i am having to fix something.
i know nothing about cars so I am back again for your guys help..

I think my timing belt just broke on my car. it looks shredded.
battery went dead and steering locked up.

so am i right in thinking it is my timing belt?

I called and the part is not expensive at all. Just $40 or so.
I called to find out about labor. oh dear god.. $300 in something.

I am just curious if this is hard job to do on this car?
I have a friend that knows a little about cars, do you think someone witha little skill could do this.

I am super stressed out and broke and can not afford this.. any help you guys can provide would be great.
