donahoe and total chaos uppper arms help

I was wondering exactly what i need to do when installing a pair of donahoes and total chaos upper arms. (not the long travel ones).I will be setting the donahoes one to two inches higher over stock. Will I need to do a diff drop? and co I need any special tools? for this install? thanks. Also what rear shocks should I use? I will be towing light loads occasionally

Head on over to TTORA and do a search. There is plenty of info over there. Be careful about posting this question though, they do not always like it when new people post questions that have already been answered. The key here is search first, ask later.
