Nah, that is all there is to it. I upgraded the ram on this computer and my old one that I sold to a friend within the last 6 months and both times went fine.
Make sure you push firmly (but gently) when placing the RAM chips into the slots so that you are sure they lock down into place (the little plastic clips on each side should lock down, and usually make a clicking noise.) sometimes they go in easy and sometimes you have to push a little harder.. but you shouldn't have to apply a whole lot of downward force.
Better to open the computer up on tile or something so that you don't have to worry about static from carpet frying something out inside the computer... but I usually just open it where it lies, carpet or no carpet and haven't had any problems.
