Just another tip, you might want to take a look at
Waila mod, its basically a better version of the things that tell you which block is in front of you at the top of the screen (not sure of what it is, I know its somewhere in NEI), it can actually tell you which mod its from and it integrates itself into NEI which makes it invaluable when searching for specific mod items and a few features for vanilla stuff, to see if a lever is at on or off position, grow state of wheat and such also). You can actually customize a key that you need to press or toggle for the mod to show you what blocks is in front of you. Best of it, you can safely use it, no one needs it for the world downloads to work from the FTB launcher since its a client mod only, it has a server thing that you need to install if you plan on using some features but its not needed either to use the world downloads (it can tell you how much EU is in a MFSU/MFE just by looking at it, same thing for some stuff in Buildcraft for standard buildcraft tanks is the thing I remember, it even tell you how much power is generated by looking at a solar panel, generator and such also... Its not finished yet but far better than the standard one from NEI...
