Can someone assist me in finding templates? Do you have to purchase all of them or are there free ones?

It's locked that you can't open it? It's locked that you can't save it? It's locked that you can't work on it?

InDesign does not lock files. If it is locked at the operating system level, you can do a Save As. If the layers are locked, you can unlock them. If the items have dotted lines, they are on the master pages.

If what you have is really a template, then the extension is .indt and when you open it, it is untitled. What is the extension?

The size of your document for the cover will be 12inches wide plus spine width plus 1/8 each side for bleed x 9 inches plus 1/8 bleed top and bottom. The spine width will depend on the number of pages of the content and the substance of the stock.

Normally you would supply the printer with a PDF using the InDesign presets selecting PDF/X-4 (unless your printer had supplied a spec),

Are you talking for printing? This is a good simple tutorial: http://indesignsecrets.com/indesign-secrets-video-laying-book-cover.php

Is the cover for a mobi file?

Based on your question, can we assume you're looking to create a Book Layout with InDesign? See link below for details.

If not  InDesign, which Adobe software product?
