Product Options and Webassist questions

Hi, I recently installed DataBridge and eCart and don't have any problems with it in terms of errors. My problem which I guess is simple ignorance on my part but I have been following all of the tutorials and have questions.

I'm not sure where to start so I'll just jump in.

I started with the integrating databridge and ecart tutorial based on some of the topics I read and that helped me figure out how to create all of the pages I needed. I'll say that I struggled with the tutorial and had to go through it several times before I got it to work the way I think it's supposed to. Maybe it's just me. The tutorial seems short and to the point so I trust that I needed to follow it to the letter so I did the first couple of times. The 3rd time through I figured that I had to change the Product and Order table names to product and order otherwise either the code was broken or it created extra tables. Anyway, doing that helped me. Maybe I missed something though.

So these pages work fine after I did that tutorial but my order form needs flavors and sizes added to them. Someone recommended the ecart tutorial and although it has more details than the databridge and ecart tutorial it doesn't talk about how to add variations to the orders.

I then ran across the product options with ecart tutorial and it recommends using the free mysql database. So I downloaded it and installed it but then most of my columns were missing. I started comparing the tables that the databridge and ecart tutorial create and the free database that ecart recommends to use and they are very different.

I understand that the databridge and ecart tutorial only cover basics so they wont create the other tables. So my questions are.

Is the free database the wrong one or is there another database I am supposed to use? Or is there a tutorial or forum that helps with this or is this not a problem and I am just too new at this? I am lost right now and was hoping these tools made this process easier. Instead it seems harder or more confusing. DO I need to somehow combine the missing tables and columns from the free database into the databridge and ecart created version?

And also, is the product options for ecart the right tutorial for adding the flavor and size options? Or is this something I should be able to do during one of the wizards? You'd think adding options would be covered in the ecart wizard however I didn;t see anything.

Sorry for being such a noob but I really want these tools to help me out but I am more lost then ever.
