You should never worry about anything
I don't muck about with different steps. With 2-row, a protein rest is completely unnecessary and is just a pain. Likewise multiple mashing steps. It's such highly converted grain that it takes all of 5 minutes to convert the starches to sugars. So other steps would be extraneous IMO.
Now decoction and fancy mash steps can be useful for doing fancy styles. But for your basic ales, I just do a single infusion at about 150 degrees. I don't think with standard 2-row, you'll see much difference trying to hit the alpha or beta steps precisely. Plus, I imagine most homebrewers can't control temp that precisely.
I'd try playing with different base malts if you want to imitate different styles. Check out morebeer.com for some of the other options for base malts that will give very different flavor profiles. But, in general, I wouldn't worry about the numerous mashing steps. I've tried it, but don't see any benefit to the finished beer.
