Your gear is absolutely good enough for Naxx 10. If you know the instance in and out, you could also do well in Naxx 25.
Given that PUGs often have ridiculous requirements, i suggest you either join a guild, or just go with the non-full-epic raids. Those may quit after half the instance, but it will already give you a chance to further boost your equipment and gather knowledge about the instance. (from a Mage POV, 10 and 25 is basically the same)
Also, try looking through this thread for any equipment upgrad you may still get from Heroics:

you're missing a couple enchants as well. If I were you, I would focus on getting wyrmrest accord rep so you can get the boots that they sell.. They'll last you into naxx 25 at least. Your gear looks.. at least okay enough for naxx10. You probably shouldn't be trying the Emalon fight in VoA... it requires a sick amount of DPS from everyone involved.. it may be a bit out of your reach at this point, and that's why people leave groups after they wipe on him.. he's not a terrily hard boss, but he requires intense DPS from everyone in the group.
also.. any purely yellow gems you have should go to 16 haste rating, not 16 crit.. Arcane mages itemize for haste over crit.. I know the headpiece you have is from naxx, but you may want to go for the
Hat of wintry doom. It's a tailoring pattern, so you should be able to make it. It's not quite as good statwise as your
Cowl of winged fear But it has that all important meta socket, which you need to put
this meta gem into. You may lose a bit of SP, but that meta gem should not be ignored at all. It will also allow you to drop some HR from other gear if you need it. Maybe you can get a different trinket besides that mark of the war prisoner and still be hit capped.
