The hard drive is easier, and less sensitive than memory. Neither is difficult. And the iFixit tutorials are really top-notch. Memory is very intimidating the first time you do it, no doubt. I started working with it when it was EXTREMELY static-sensitive and never blew a chip. Take your time, sit down, touch the case while touching the screw on the cover plate of a light or electric socket to discharge yourself and you should be fine.
Honestly, the most difficult thing in servicing a MacBook is the case screws! It's very easy to cross-thread them when screwing 'em back in and getting one protruding a bit. Very inconvenient. They're very short-throw screws, so it can take some patience getting the cover back on. And on the Pros, and I expect the Standards, there's 2-3 screws that are approx 1" long whereas the others are less than 1/4" long, so you have to keep that in mind. The long ones are on the hinge side, so even that is kind of obvious and not hard.
The important thing is having a proper #00 screwdriver. And if you ever need to replace a battery, you may need a Y-blade screwdriver, I had to buy one of those from iFixit. The little repair kit from them that's about 6x6" is very nice and quite useful.
