SohoLaunch Integration Into Existing Site

I set up a basic site using html and css. I want to integrate ecommerce and a couple other things that look like they are available in SohoLaunch ("SL").

I installed SL when through Fantastico.

I have several questions:

1. Is it possible to integrate SL and use the Shopping Cart functionality and other select pages without using the whole application? In other words, keep the pages I already have and just link to Product and other pages created by SL?

2. Is it more trouble than it's worth?

3. If so, how can I uninstall SL (I'm leaning toward Oscommerce anyway) - I see no such option in my CPanel/Fantastico panels (for that matter, I see no install options for any of the Fantastico choices either); although Fantastico reports SL as installed.

4. Either way, SL is not coming up properly when I go to website/sohoadmin -- after I enter the name/password I just get a page saying application is loading, but nothing more happens. I suspect I messed up the file structure while figuring out how to use dreamweaver, and I'm probably missing needed files. Therefore, back to No. 3 ...How do I uninstall, especially if I cannot do so through Fantastico?

Thanks all,
