Tracking expenses during business organization

I'm in the process of starting a "sales and marketing" company that has our own product line. We will be selling apparel wholesale to retailers and companies/organizations purchasing promotional items, as well as directly to customers online.

In order to start the company, I've incurred expenses such as the purchase of sample products, shipping, travel, domain names, and other developmental necesities. These purchases have mostly been made with a personal credit card, and the remaining paid with personal checks. Currently, I do not have a business bank account. I'm delaying our LLC filing fee ($800) as long as possible.

My question(s) are:

1) how should I categorize myself in our company's Quickbooks file? Am I a vendor that should invoice the company?

2) How are websites, hosting, shopping cart, and other fees categorized in Quickbooks?

3) What about monthly subscription fees that I'm currently paying out of pocket?

I would also like to set up a personal QuickBooks file. Can anyone offer suggestions on doing that efficiently? If anyone's up to it, the most helpful thing to me would be a screen shot of an existing Chart of Accounts built out for these or similar purposes.

Thanks in advance for any help/insight offered.
