Kanku Chikatoku Ticket

I read about the Kanku Chikatoku Ticket for travel from KIX to Namba and change to any subway to my final destination for only 1,000 yen but I could not find any further information about it. I'll be visiting Osaka in March 2018 and will be arriving at KIX around 9.30 p.m. and will then proceed to my hotel in Shin-Osaka. Hope someone will be able to answer the following:
1. Will I be in time to clear immigration and customs to catch the last trains and subway to my destination in Shin-Osaka?
2. Is the Kanku Chikatoku Ticket still available in 2018?
3. If answer to Q1 an Q2 are YES, how/where do I purchase the ticket and will I be able to purchase one at KIX on my arrival at such a late hour?

It is too nervous to worry so early.

2)
Yes.

Why did not you read the official website?

1) 3)
No problem, unless serious delay in the airplane,
You can purchase at ticket vending machine of Nankai Electric Railway's. (Not JR's)

Hi Mihas,
Thanks for your reply.
The reason I'm looking for info so early is because if I book the ticket that arrives in KIX late in the evening, I can get a cheaper fare if I book early.
As for not reading the official website, I have searched and was unable to find it. Therefore I turned to this forum which I have used since 2011 as there is usually someone who can provide the necessary information. In fact I have also provided information on travel in Japan to other visitors through this forum as I am a regular visitor to Japan myself.
Ok, anyway one more question regarding this ticket - will I get a reserved seat on the Nankai Limited Express Rapi:t or do I only get to ride on the ordinary Nankai Airport Express which is a commuter train?
