Welcome Kiwibarge.
Firstly 10' x 3' is perfect for a simple shunting layout but not for a double track oval in 00/H0 as even the smallest track requires 29" diameter & the next size up #2 requires 35" diameter and that is the smallest that some Bachmann & Hornby locos will traverse .
Note that even with 35" diameter curves, long coaches look slightly ridiculous - one modeller in the US only uses 36" radius curves - I assume he has more room.
That is where N scale stands out with diameters from 18" then upwards to 21" and nearly 24" diameter. These figures for both scales, are Peco Setrack
Secondly. DCC is the way I would go as it allows a multitude of things that DC can only dream about - of course it is dearer.
