This is correct. Blue colored crit crystals that are better than the "stock" ones you can craft come around level 100 give or take. They're called "perilous" crystals.

I for one am against an LFG tool as most implementations don't let you choose who you group with like when setting up a group. There is less "accountability" and I also think it affects how fast content is consumed. Just because something can be automated doesn't mean it should. I wouldn't mind a LFG channel to make it easier to group without spamming General though.

I'm a min/max'er and even I appreciate no damage meters. I like the extra challenge of figuring out how much damage I'm doing without the meters. Not everyone can do it so it's another way to set apart good players.

I'm finding Focus quite good too. It has great alternative perks compared to combat all the way up to level 27 or so. Combat get's an improvement to offhand damage, defensive forms, Ataru form, some Ataru form proc buffs and an automatic Bladestorm crit plus some defense to aoe and centering building. Focus gets improved crit chance to force powers, increase to force leap's immobilization, 15% crit chance buff to Slash, lower cost of Bladestorm, lower cooldown of all force abilities, a second Leap with Slash type damage, and improvements to Slash and Zealous Leap. Plus the Zen effect of Shii-jo form is awesome! Then Focus get's a up to 100% extra damage, 100% crit chance force sweep on a 12 sec CD by level 28. Combat tree gets it's automatic bladestorm crit at level 27. I'm not arguing the superiority of Focus to Combat, but I am arguing that it is a viable alternative depending on how you'd like to play. I find the "people on your server suck / you suck" arguments fruitless and banal. Look at the trees objectively, then go out and try both before issuing blanket statements that are flat incorrect.

From my understanding the Crippling Throw immobilization works. It's Debilitation that is bugged.
