<{POST_SNAPBACK}>I haven't decided yet what to do regarding points, but if decide to go for DCC control of points what kit would I need please to allow this and is it essential to convert points or can they be left as they are
Not essential to control points by DCC at all and often preferred by many not too. I personnaly am providing some form off DCC control of points to enable me down the track to hook up a computer based control system.
Point motors of any description can be left in place if you are happy with them and as mentioned in other answers some form of stationary accessory decoder would be required to comunicate between you DCC system and the point motor.

<{POST_SNAPBACK}>Similarly the same for signals
Same goes here. I am not sure if you are referring to colour light or semaphonre but you can control everything with DCC if you really want or you don't have to if you are happy with how it works. DCC Offers similar opportunities for block detection and signalling but nothing that can't be done in DC.
