You are on the right track.
I just hope this phone came to you to try and repair not data recovery. Please don't mess with someones memories, for now try and learn on your own phone or damaged phones bought on craiglist/ebay.
A good source of knowledge for the iPhone repairs is Jessa Jones at Ipad Rehab
Data recovery or complex repair on the iPhone motherboard requires skills in micro-soldering and good tools.
