Powerstore / Dreamweaver

Hi I need to build a website with an integrated online store. Currently the website is www.angelicwishes.co.uk - I used your Paypal payment buttons extension for this purpose, the store is built in Dreamweaver. This has worked reasonably well - the site is still something of a work in progress and I need to make some drastic changes. Firstly the site needs to retain its information content and also have the current static online store integrated into it with its own shopping cart rather than the Paypal cart. Also I need to hand over the site so the owner can add products easily, which at the moment is a time consuming process in Dreamweaver handled by me. To this end can I use Powerstore's core functionality but reshape it as I see fit in Dreamweaver by changing the supplied CSS and also adding in custom elements to the home page directly within Dreamweaver?

The plan is to have product on the index page along with additional information and a link to the main store based on Powerstore. I am happy to roll my sleeves up and change CSS in Dreamwever etc - but is this possible without wrecking the functionality of Powerstore. Also are the store product pages generated from a template whereby I can do likewise and change the look and styling of the templates without breaking the functionality. This way I can retain most of the look of the website (I except that the product pages will not be exactly the same but can be re-coloured close). This way I can hand over the website and let the customer add products as they see fit without me having to code everything. They also get their integrated shopping cart facility as well.

I am not after a walkthrough - just want to know if this heavy editing can be done in Dreamweaver without the whole functionality falling apart?

Many thanks, I look forward to your response in due course.
