Grammar, Usage / Confused with MLA format and in text citations! [19]

Ahh I hate this part of reserach papers!
I don't know when to use an in text citation, for example
The Humean Theory of Motivation states that the motivation for an action requires desire; belief on its own doesn't suffice. does that require one?

and does this? The Merriam- Webster online dictionary defines it as conscious impulse toward something that promises enjoyment or satisfaction in its attainment

Also, when making a work cited pg- do you make it like a bibliography or only put the in text citation things?

How can I make these into work cited mla:

Research Papers / Need a catchy funny title for a paper on desire causing motivation? [6]

for example, someone is doing law/ government and the title is law without order- a catchy name based on the hit tv show. if you can think of something that would be great!
