VOA for NewZealanders at Delhi??

Hi - First time to India for me.....but am well traveled

I will be entering India at Delhi and am eligible for a 30 Day VOA.

I plan to arrive in Delhi on the 8th of Dec and catch a plane that day down to Dabolim and then on to North Goa where I will be attending a Yoga retreat for 2 weeks.
Have a return flight on the 23rd to Delhi and would like to take in Agra, Varanasi and a couple of destinations in Rajasthan before flying out of Delhi on the 6th of Jan.

I have a few questions that I was hoping some of you experts could help me with? :-

1) The VOA has a few prerequisites, the usual Passport conditions plus showing evidence of enough funds for 1 month in India - can I just show them a wad of Cash, my Credit Cards or a letter from my Bank? I have read that this process can be quite a chore.....any Kiwis out there that can comment on how smooth this was for them?

2) Am I being unrealistic with the amount of destinations I would like to cover in 2 weeks? if so what would you suggest. I would love to see The Taj and Varanasi, so if time is limited what is considered a 'not to miss" destination in Rajasthan?

3) Being Xmas time and NY, should I be looking to make all my bookings for accommodation and travel (Trains and Planes) now?

4) Would there be any preferred order or route that I should follow if any?

5) Previous to arrival in Delhi I will have spent 3 months Trekking in Nepal and will have excess baggage not needed for the month - is there anywhere at Delhi Int'l airport that will offer storage that is safe, secure and reliable?

Thanks in advance for any suggestions or help offered.

Cheers.
