Will I need any type of license for re-selling merchandise (hands-free) through an Online wholesale Company in my state of Pa?

There are several things to consider when one decides to start up a business, and a few perhaps-unexpected wrinkles when the transactions are going to be online.

First, would the business be organized as a corporation, LLC, partnership or proprietorship? Will it be entirely "virtual" or will it be "clicks and bricks?"

Our website at Internet-Atty.com provides an outline of the special considerations for doing business online. (See link below.) These include dealing with terms of use of the website and figuring out the business model of getting paid. The shopping cart model is good for individual sales, while "free" has been working well for Google, et al. See the link to a book by the editor of Wired Magazine, Chris Anderson.)
