Help changing homepage template [noob question]

After looking through the forums here and not finding an answer, I thought it would be time to ask. I am completely new to this site and honestly, the whole process of setting up an online store.

I purchased and had installed the following template:

http://www.templatemonster.com/zencart-templates/39691.html

I have gone through with the Zen Cart admin panel and customized all of the pages how I would like them, except for my home page.

Using photoshop, I pretty much replaced all of the photos and text but they are still in the same spot and would link to the same places (I don't know if moving location would change the links). How would I replace the current homepage with my newly edited homepage? Is there anything I need to look out for when doing this such as problems that might arise?

I know my questions might seem elementary but I am still learning and reading up on things. Thank you for your time if you answer!

You have selected one of the worst suppliers for a ZenCart template that there is

They take license and hard code many things so that builtin functions do not respond

You did not provide a link to what you have so any suggestions would be guessing

Ouch, that's not good. I am on my laptop at the moment and will update the OP with what I am wanting to upload. Thanks for your reply.

Well, never mind, you can't let edit here. This is what I am looking to replace the home page with.

You will have to find out where they have these things hard coded to be able to change them
