Hi Cody,
if your content is good (it includes relevant keywords and phrases), and if you're using the most important tags properly (title, h1, h2 etc.), you should be fine.
One trick you can use to help with internal linking is to create a html sitemap of your site and link to it from the footer. The sitemap would include keyword reach links to the most important pages of your site (for example categories and subcategories).
Hope it helps.
