About to buy Powerstore 2

A question or two before I begin the purchase/download. I've read through the What Do You Need to Start, did a bit of preliminary work. I wanted to know if I need to do anything else that will make our transition easier. We already have an existing html site. We want to add the shopping cart/store. We started off with oscommerce, that was a nightmare.

What I have so far: the mysql database on a linux server. Our cpanel does come with MYPHPadmin already installed--on our remote server...not on our local computer(s).

Reading through the prep materials, it sounded like I need to install PHP on our local computers as well? Or do we use what is on the remote server?

Are we able to preview the shopping cart pages right from dreamweaver? When working with oscommerce php pages in dreamweaver, it wouldn't preview. I was told I need to set up a WAMP server to preview php pages, but I have no idea how to do that.

Any help will be greatly appreciated. I look forward to learning new ways to tax my brain...

Thanks,
Michelle
