Greetings and Salutations !!! After mastering my lawn, I have now ventured out to flowers ... perennials to be exact. One of my flowers from last year is the red-hot poker ( Kniphofia ) and several others with long, tall striking vertical blooms, I did not cut back any of the stalks. My question is ... should I now go out and cut all of the spent stalks down to the foliage? Is that what deadheading is? If I do, do they grow back or do brand new spikes come up?
Yes. Deadheading is cutting back the stalk to the base or some just cut it off below the faded flower during the summmer. Now, after winter, you can cut back all the dead foliage and stalks. It will all grow back!

we thought birds were eating them as the seeds are disappearing within a day or two
It would be hard to say without catching the creature in the act! It could be birds, insects, or a number of other animals.

I just bought a Red Hot Poker Plant in New Mexico. I live in St. George Ut. I planted the plant in a sunny area with room to grow on a layer of potting soil. The leaves are starting to turn yellow. I have watered it and even applied ice to keep it cool. What more can I do to save it?
Red Hot Poker likes full sun so ice isn't necessary. Yellowing leaves could be a sign of overwatering. It is not necessary to water every day. Let the top inch or so of soil dry out between watering. Also, they do not like wet feet, so well-drained soil is a must. Here is more information on their care:

The plant was a bargain and I noticed that many of the leaf tips had turned brown. On further inspection the leaf tips appeared to be a pinkish colour. Should I remove these or is it normal?
Unfortunately, your photo did not come through.
This can indicate an overwatering problem, or even some nutritional deficiencies or even too much fertilizer, depending on how it looks.
The first steps to take will be to test your soil for deficiencies or pH here are some articles that will help:

My red hot poker is getting clumped together. How do you detach and replant elsewhere.
Red hot poker doesn't really like to be divided, but you can separate the offshoots that grow and replant them. If you must divide the whole plant, wait till spring and divide it into sections, with a good rootball for each section. It may be 2 to 3 years before the new plants bloom.
Here is info on how to care for your plant right now.

In reading your article about Red Hot Poker care, it appears that the information contradicts one another. I have attached two photos of the article. Which is correct??
Both! Depending on where you live, you may need the extra protection through the winter. Otherwise, you can prune in Autumn.
I think that it would tolerate those conditions, but you will want to be mindful of watering. Don't let more than the top 1/3 of the soil dry out, completely. Don't let that top 1/3 stay wet, though.
This article will help you to know what care that these plants need:
