For complete times from Forest Hill for both types of service the National Rail search site at http://pda.ojp.nationalrail.co.uk/en/pj/pj or the live departure board at http://pda.ojp.nationalrail.co.uk/en/pj/...rd/dep/FOH are the only current solution I know of. Those URL's (mobile phone friendly) both cover services from FOH to HHY as well as LBG. That's something I have not been able to get out of the TfL online services yet which seem to ignore the national rail services.

If you want a printed version incorporating both it suggests contacting National Rail may be the best chance at present although TfL may catch up at some point.
