Easiest is definitely best. I am not sure about the bypass
requirements (what does this mean?). It is a Baxi Solo 3 50 PF (gas
fired), but the manual does not mention this.

Probably doesn't need one then. A bypass is a means for water to
circulate through the boiler core after all the valves (TRV or
motorised) have shut. Low capacity aluminium boilers can go into melt
down if you just switch 'em off and stop the water flowing at the same
time. Larger and/or cast iron boiler don't object.

I am actually hoping for a single timer with fully independent
control over both systems - am I right in saying that the wiring
would be a little simpler ? I would like to be wireless everything.

Wireless adds pennies, quite a few pennies. If the pump, motorised
valves, wiring centre, programmer and room stat reciever are all in
the air cupboard they can be all hardwired. Wires are very reliable.

If stats are necessary I will probably get a cylinder stat as well.

I wouldn't run a system without tank and room stats.
