I've had the pleasure (yeah right) of having to replace both front outer boots this summer, I found it easier to use the inner boot removal method. But if you go that route you need to be sure and get replacement clamps for the inner boot because you won't be able to reuse the old ones. I did some research and found a company that sells the bands that come with the boot kits, link below. As for the tri-head bearing, don't worry about it, it will come off, I used a small light weight hammer to tap it off, nothing too heavy. And don't worry if you knock one of the bearings off, they are just pressed on, just tap it back on. Also you will need to replace the grease in the inner boot, it's a different type of grease than the outer boot, it's a thinner grease used for the needle bearings in that joint.
