Post Template

I am looking for a way to make a post template. I use the ATA theme in two ways on my site. Front page is a standard blog. Deeper I have a page template that accesses another database to create specific pages. Populating this additional database does not allow for a search of both databases concurrently. I would like to make the page template a post template that would put all the info in one place, allow for viewers to access both post types together and make it more SEO friendly.
Main page: www.ToDoInThisTown.com
Page that I would like to make a Post Template: Location Page
Is this fairly straight forward? Does this require substantial customization?
