This will be the first time I've replaced a chain. I have a 2012 SRAM Rival group set. I've probably ridden it close to 2000 miles, with few hills but probably a lot of bad pedaling from my early days (shifting under heavy load, cross chaining). The chain isn't yet at the 'stretch' limit -- as measured with a metal ruler, 10 links are only about 1/32" too long, but there's some noise despite having the derailleurs properly adjusted, and I'm engaged in a general bout of bike maintenance.

I see a lot of positive reviews of KMC chains. Would this https://www.amazon.com/KMC-10-Speed-.../dp/B001AYOP9M be a good choice?

SRAM also makes the 1091R, 1091, PC1071, 1051, and 1031. I assume that the higher numbers are higher quality and lighter. Would a SRAM chain likely be quieter and/or shift better on my SRAM cogs? Which of these SRAM chains are the best price point for a casual enthusiast -- I doubt I'll ever need to change my chain more than once a year, so I don't mind spending a bit more, but I don't need to waste money.

It appears all the chains I'm looking at have a master link. I have a simple chain tool on a multi-tool I just bought -- I'm assuming this is all I'll need, correct?

I'm using this video as my main guide: How to replace a chain - BikeRadar USA
If the rear is still a little noisy when I'm done with this, I may also replace the rear cassette, but that seems excessive right now. Thanks in advance.
