Chris could you send me some links to wiring the system from start to finish.
You are asking for potentially a lot of information. You will have to supply a lot more detail first.
OK the info you have supplied so far is [items in bold]:
Controller = RailMaster and eLink [but what power pack ... the default 1 amp supply or the 4 amp upgrade supply?]
Point motors = DCC Concepts iP Digital point motors [but how many?]
Point motors .... iP Digital have manual over-ride capabilities and auxiliary contacts ... do you want to make use of these optional features and in what manner?
Are you intending to deploy a DCC BUS system?
What do you mean by track lighting? Do you mean generic layout lighting such as platform lights, internal building lights etc. If so, what form are these going to take?
Signals .... there are so many different variations and control methods you will have to specify brand and model numbers, as each will have different wiring requirements.
