singring, the good news is you don't have to adjust these new chains very often. I won't go into the best cleaning and chain lube info as there are a ton of threads already. I would search these as well as those covering Scott oilers etc. if you are so inclined.
Too loose is better than too tight!
You can do the roll and repeatedly check tension test to locate tight spots. A friend can help balance the bike on the side stand while you rotate the wheel. Most have purchased a bike lift from stores like Sears, Harbor Freight etc. I've seen posts on homemade wood lifts that look like they would do the job as well.
Others will chime in. Here is another good site to check. Great guys that post in both forums.
