Hi and welcome to the forum. BTW -- new members aren't allowed to post links unless Ben approves them. He was not online at the time your post came in, so I deleted your link so I could mod it in.
Yes to using BBB rather than pool store chemicals. Will save you a ton of money and do a better job for you. Read a lot of the stickied threads at the top of many of the forums (especially the chemistry forums) and also go to our sister site www.poolsolutions.com and read there. Lots of good information to help you get started.
The kit we recommend you buy is the Taylor K-2006. If you order it through Amazon at the following link, Pool Forum makes a little money which helps us stay online.

I'm going to see if I can find a picture of my steps to show you. I would not advise drilling holes in them because if you ever get algae, you'll get algae in the steps as well and that will be a pain in the rearend. EDIT -- I found a link that shows a similar type of ladder to what I have in my AG pool.

I have a 3-sided resin lattice fence that is around my pump to kind of hide it a bit.
Hope this helps.
