No need to stay near Thicksey, It is a short distance from central Leh.

Not more than 500 and that too with frequent landings between. Take your time in climbing the stairs and rest between taking a look around. The place is a must to see, dont be afraid of height.

You can directly bring your vehicle to the entrance gate of the monastery and buy ticket from there. It's a 12 storied monastery so you have to climb up,but take rest and lift the stairs.

I think you would need to check with the monastery direct

I would recommend you to visit Ladakh during summer months (Jun/Jul being ideal).. in fact right now I'm on Ladakh trip.. it's already pretty chilly out here and with a kid you would require to be more cautious.. best route is from Manali side as it offers amazing views enroute and it's a beautiful drive no doubt.. although I'll suggest you to check the weather forecast and road conditions before planning as it is frequently marred by landslides..

Best to fly to Srinagar and go by a beautiful road to Leh via Kargil and Alchi. Return direct flight from Leh to delhi.

I think you mean to boarding is "Entry". It was INR 30 that we paid! It was the fee for a single day. If you want to stay there for a night or multiple nights then you have to contact thikshey monastery directly.

You can actually stay inside the Thiksay Monastery. I don't know about the process which needs to follow but Thiksay monastery is amongst those monasteries which allow visitors to stay for a limited time.
