I want to post a book and i put in the ISBN code and it shows up paperback, now closest one to it is a hardcover with large print, but its a hardcover with normal print. So it tells me i have to put the book into the system...Should i just put it in the system or should i list it as a paperback?

You need to list the format that you have.  If the book that you have is a hardcover and the ISBN pulls up a PB, you shouldn't post it. 

If the binding and the ISBN do Not match then most likely you will have to list it manually with a shortened PBS generated number that is for that book only.  When you do that you can go to a vrsion of the booik that most closely resembles it it in binding and and title and author - put a tag on it that says it's " available with ISBN#_____" and put in the PBS number that you listed it with.

When listing a book that states it is Large Print, the system asks you to confirm your book is LARGE PRINT (16 font).  If not, is has a CLICK HERE link in the text.  When you click that it pops up a box asking you to confirm from several choices:

ISBN is correct and book is large print

ISBN is correct and book is NOT large print

and a few others I don't remember

Select the correct one.  If the listing you have pulled up is large print and your book is not, you will be given the screen to enter the book details after selecting the appropriate response.
