Fast trains usually stop at Reading and no where much before it (sometimes Slough iirc). Slow ones will stop at Twyford or whaterever it is that the Henley train goes from/stops at. So for the cheaper one you'd always need to be on a slow out of London which can take some time.
Dunno which is quicker in the long run - going to Reading first or not.
The train to Twyford is painful - although doesn't seem to be a lot of benefit timewise going via Reading - 56 mins vs 1h 3m. If you don't go via Reading, you need to change at Slough, then Twyford so it's 3 changes which is a bit of a pita.

You might be better off living in West London - The Twyford train stops at Ealing Broadway I think and then you can drive once you get your car. It's not too bad going out of London, especially if you're not going in as far as the North/South Circular
ETA: which is pretty much what se5 said
