1. Can I develop my HTML/CSS and template files in DreamWeaver and "transform" them into DNN files? Or DW is still needed at all?
you can either develop skins or module content in Dreamweaver and convert into a skin or past into HTML module (using inline CSS)

2. I used to store my product data in DB, and then dynamically read the data from DB into asp page. Can I still do this with DNN? Such as keep my part of code for asp DB data rendering in a DNN page.
In your DNN module, you may use any ASP.Net webforms code you like, usually DNN accesses the database either using a database layer calling stored procedures or using Linq2SQL. MAybe you want to check out online tutorials at dotnetnuke.adefwebserver.com.

3. I'd like to start with the community edition. But can this edition use most of the app modules existing in the market?
All modules I know of are for Community Edition. Be aware, that Modules for DNN 1 and 2 will not run on DNN 3 and above, while DNN 3 module in some cases won't run on DNN 4 and 5. Most skins work in any newer DNN version since DNN 2
