Large Scale Central

What power and electronics should I invest in?

I am looking to find out recommendations on what power and control electronics I should purchase.

I am looking to build a garden layout in the future and I am starting to investigate what are my options. I have been collecting G scale trains (Aristocraft, USA, LGB) for about 10 years and now I want to set up my outdoor layout.

Requirements:
I would like to be able to power multiple trains - not on the same line - but potentially keep it as an option.
I would like to be able to control sound (have not invested in any sound capabilities as of yet - but I want to)
I would like to be able to control the trains while walking around (hands-free).
I would like the capability to control accessories (lights and switches) remotely.
I am not looking at cost at this time because I want to get what is right for this layout that I plan to keep for years to come.

Any recommendations would be helpful. I know this is a broad question but any input would be great.

Thanks!
