Sorry to cause confusion apache. The point I set out to make was 'don't do as I did', as I have ended up with a great riding bike, but not one I would wish to commute on.
What I have learned is that 'race geometry' means twitchy, fast steering and hard on your backside, so look for the phrases 'more relaxed' and 'sportive'.
One thing to remember is that frame sizing mtb to road is different. I was lucky as my son is the same height and build as me, and he had a Bike Science fit done some time ago, so I knew that a bike that suited him would not be a million miles away. It's worth a trip to a good shop, preferably one that specialises in road bikes, to get an idea of your ideal size. After that, the bay is your friend (caveat emptor), or do what I did, and look in the roadbike for sale section.
As for bars and angles... it's all Greek to me too. The Raleigh was set up with a tape measure, and I really had not realised that the hoods / levers were pulled up that far. I have now rotated the bars forward so that the hoods are more level.
When I started riding the Raleigh, riding on the tops of the bars was comfy, and the hoods were a little bit of a stretch. Now, the hoods are an easy reach and I commonly have my fingers wrapped around the front, so an adjustment was just about due, even if I did not realise it
