Mid to late May, or early June. The "prime" time to climb Stok Kangri is usually given as mid-July to mid-August. But usually by that time, there won't be much snow up there.

Yes you can. It might help to have a porter/man with a donkey/mule carry your stuff up to base camp though. My friend and I tried to do it all by ourselves in May, but got turned around as my friend got sick. We had planned a trip of ~8 days.

Foreign nationals will need to get a permit for ANY peak in India. Stok Kangri is a trekking peak, and hence the permit fees are much lower than for other peaks, for which they most often require that you be part of an "expedition". Again, since its a trekking peak, you could climb by yourselves (i.e., no need for expedition leader, liaison officer etc.), but you will have to get a permit. I don't know the details of current permit fees, and it looks like the web site of the Indian Mountaineering Federation is down as they have not renewed the domain name .

I don't have any useful info on this topic, but I'm guessing there should be lockers available in Delhi airport. Alternately, if you're planning to stay in a hotel in Delhi, drop your stuff off there before you head to Ladakh. They'll be happy to hold it for you for no extra charge. I would rather do that than use lockers.
Have fun in Ladakh, and post a TR when you come back!
