I need help with determining the parts of speech w/ this sentence!!!!

This is terrible.  You're gonna fire me.  I can only find "one" listed as an indefinite pronoun, which means it has no antecedent; but in your sentence it has an antecedent  -  yearbook.

"Paid" is either transitive or intransitive.  In this case it's supposedly transitive, as in "to pay taxes."  That means it takes a direct object.  So what do you pay here?  "for one."  Again, a prepositional phrase is direct object of the verb.  (I don't really like it.)  Who thought up this sentence, anyway??  It's very short, but it packs a lot of trouble.   - A.

so what kind of pronoun is "one"?

 

This link has a really good description of all the uses and forms of the word "one"

Excerpt (applicable in this case)
Sometimes the pronoun one functions as a numerical expression:

Those are lovely scarves. I think I'll buy one.
One is hardly enough.
One is purple, the other green.
The three brothers get along quite well; in fact they adore one another.
One of the senators will lead the group to the front of the capitol.
The yellow car is fast, but I think the blue one will win.

There are various diagramming techniques - this link describes one with a nice powerpoint presentation

 This is the best I can do with your sentence and the limitations of diagramming  with text on this site
