Well, the first thing you will want to do is get all the information you'll want for each topic. This way, when you layout the database tables, you don't forget anything. I usually sketch them out on a piece of paper so I can show relation if I have to, and the visual makes designing easier anyhow.
I would make each topic it's own table. The support groups table could be linked to sub tables which contain the information you want for them (relational).
Once you've got all your information inputted into the database, it's not hard to make a web front end for it using DreamWeaver or FrontPage. You will have to make sure your web host supports whatever scripting language you use though. Almost all web hosts support java and php, and most good ones support asp. You might even be able to purchase a premade data display front end for the data. We have done things like that for customers in the past who have their data and do not wish to migrate.
All you really need Access for is entering your data, but it might help to learn how to make forms for the data entry. I usually don't waste the time anymore and just enter it in through the dataview itself. Depends on if you want other people to be able enter data or not, and how easy you want the process to be for them.
I'm sure none of that helped, but if you have other questions, shoot!
