I have no experience with that trigger, but I can tell you it is not difficult to do. Replacement of the trigger group is really just a few minute job. It's not the Chinese finger puzzle it appears to be.
Here's a video that might help:

Really, a 5/32 punch and a small hammer you got this. I installed an RTB enhanced trigger group last week in my bathrobe on the sofa. No vise, no laser tools, just a place to keep the parts where they aren't dancing away and you are good to go.
