The toothpick method works for me; the main thing is making sure your rings are clean and lubed.
The color of the o-ring almost always identifies what material it's made out of. This is important to note as you want to avoid putting silicone lube on silicone rings (they're usually red.) Most folks who replace their rings go for glow-in-the-dark; head over to the CPFMarketplace and search "Sigman GITD" for one of the largest selections.
First time I used a toothpick w/dental floss like mentioned below but later found out it was doable with just a toothpick - I guess it just depends on how much flexability your O-ring can stand.

It will then be easy for the o-ring to be pushed/rolled over to the inner groove because it can’t fall deep into the first groove. Take the thread off and put the next o-ring in the outer groove.

As far as where you can buy O-rings see if you can contact CPF member run4jc as he made a purchase some where and had many to give away.
Thanks to run4jc I now have a choice of red and black O-rings to dress my
I decided to try out the white rings on my droid biner last night...
And I left them on there because they look cool...
I've found that 011 rings are a little easier to work with...and it makes me appreciate the lock-out feature a LOT. The 010 ones are a more snug fit and more difficult to install/remove (both on the 007 and the droid), but probably more low-profile as far as accidentally turning on in your pocket.
For the droid, I didn't notice any difference in resistance between the 010 and the 011 rings.
