Old-school programmer wishes to get up-to-date

I last programmed about 15 years ago (for about 15 years) in 3GLs when the web was in its infancy. For years, I have tried to figure out the best ‘starting point’ to play a little (or lot!) of catch-up to current technology. I have a bit of OO programming in my background, as well as SQL, so I don’t believe I’m a total novice.

Where is the starting point for programming on the Web? For simplicity’s sake, I’ve rather arbitrarily chosen the Microsoft platform of tools. So should I get an ASP.NET book? Should I go more basic and learn HTML first? Should I try out a product like DreamWeaver (I know this is not MS). Frontpage? Is there any “hierarchy” to any of this?

Thanks Loads!
