I did read the guide, and in fact have been shooting for the list of best non raiding gear for the most part. I am also doing pvp though for gear which the guide I think does not consider for gear, and also not speced
for what the guide maximizes for so am not 100% sure just how closely I should be following it.

As for the items in need of upgrade. I am assuming it is my two blue mana-etched items, the helm and gloves. They do give a nice set bonus though, so it may be hard to split them and upgrade them.

I was in a small guild so had to pretty much solo and pug whatever I could. Now after almost two months at 70, I recently joined a larger guild but am not getting invited to any raids as of yet, so I want to be geared as best I can so I am ready if/when I am ever am or to go shopping for a guild that will include me more. I also have a pvp set of gear and I hope to work on that some more soon as well. I almost always use my imp.
