As above norm would be to look at various commute routes and drive to a good station. You need to factor in traffic and parking options (inc costs) too. Riding to station could be an option and/or Brompton (edit: I see you are onto this !)
For example when lived North side of Guildford I drove to Woking (similar drive, shorter train journey, more trains, cheaper parking) when I moved to central Guildford I walked/drove to main Guildford station.
Good luck, Surrey is a fantastic county to live in and to combine leisure and work. Close to airports and Channel Tunnel etc
