Yep, that's my pool, too!
I did not get a liner. Since it was only used for me we just cleaned it out and sanitized it after - though I did not actually birth in there. If I had I probably would have just thrown it out.
You need a drinking-water grade hose to fill it up. I ordered one from Dr. Foster's and Smith - it's a pet care website that has aquarium hoses for a reasonable price. We also needed the adaptor for our sink. Amazon.com also has some "RV" hoses but I have heard those produce a bit of an odor.

We also got a water thermometer - if you plan on birthing in the tub you need to maintain proper temperature.
A small fish tank skimmer comes in handy for, shall we say, *floaters*
To keep the water warm we just kept the tea kettle and a large pot of water heating at all times and added them when needed. I was surprised at how warm the water stayed, though.
There is a sticky in this forum that has a very comprehensive list of homebirthing supplies. I found it most helpful!!
Congrats and happy birthing!
