Actually, I don't slot the yellows unless I'm doing tanking, or the zero cooldown mark is a must have for the fight. That said Defiance (a class quest one), and Tactical Prowess are the two most commonly picked yellows. Others like Composure, I don't use it, but it's another trait to consider.

Blood of Numenor is best ground out with a group of players that needs to work on their rez traits, and having a suicide party. You could also group in the 'Moors and rezzing people (it goes FAST with that).
As far as reds go, getting Expert Attacks, Adherent of Elendil, Battle-master, and Renewed Voice is all you really need. Turn of the Tide is nice for the stun, but the rest of the red traits suck pretty badly.
Hopefully that helps with the traits and what to focus on grinding.
As far as virtues go, I like a lot of Tactical Mitigation from them, but this is where you fill holes in your build. You can find out more info at http://lotro-wiki.com/index.php/Virtues. Clicking on a specific virtue will give you a list of deeds needed to rank it up. Or you can just dump money and buy the ranks you're missing (not recommended).
If you can stand PvMPing, get two pieces of perserverance. If you can stand PvMPing after that, grab 4 pieces of Command to suppliment the Perservance. Also grab 4 pieces of Hytbold Healer armor, to suppliment the Perserverance gear. That's about the best you can do for raiding.
Bells of Dale for the cloak and earrings, Get enough rep to get the might-crit proc ring, get the might/crit pocket from Sambrog. I think there's a might/vit/tactical mitigation necklace from Thadur as well, which is a solid slot for the necklace. The ToO DIY Might necklace is a useful one too. otherwise, get enough fate that you don't go OOP, but focus on might and crit without sacrificing your morale or mitigations too much. Don't worry about physical mitigation, it will (largely) take care of itself from armor and might.
Hopefully that gets you started.
