But you don't need to gem any item until lvl 78 or so.
Respectfully disagree. In outlands you can get easy quest greens in your lower 60s that have sockets. Putting northrend greens in the sockets make them so much better than anything you can get at the level. ( For example http://www.wowhead.com/?item=27715
quest reward available at 60, 3 Sockets!)
The same thing applies to late 60s blues. For instance, http://www.wowhead.com/?item=31105
is an awesome helm that you can get at 67 (I had a lock summon me (on my DK) to the area you usually fly too) and it will last you till you get to mid 70s (till Horned Cobalt Helm at 75)
With how cheap northrend green gems are there really is no reason to not try and get the outland gear with sockets. Sure at 80 it all gets replaced but it makes the leveling grind that much faster.
