Try to cover everything I could remember, but I just smoke some JH 
Plus I'm not an expert like many on here.
The plants that the stem collapsed & it just died, that's post-emergence damping off, basically some fungi taking hold of your shiat! here's a link for prevention, basically more sterile, more air/light needed. My problems with that went away when I germed faster with heatmats, used seed starting soil right out of a fresh bag, humidity at first but then gradually got 'em dry. here's a link that's more detailed about damping off diseases http://tomclothier.hort.net/page13.html
Looking good in the pics but I would fill the cups up level with your starting mix, & hit 'em with some ferts, 1/4 strength miracle grow or whatever you can, but feed em & try to get them into full sun as fast as you possibly can.
I have seedlings 1-week from germ, many af's (Mostly LR but some Blue Him & Onyx) and a few PPP's, SK#1's, some free fem's, and a few others. Right now they are all in FULL SUN (Except for 5 yesterday, probably 2 today that were still to young, out of like 70) for the whole day, then when no sun in my yard but still light out they go under T8's, until I remove all of the non af's for a 5-6 hr' rest but the af's are under the T8's all night. Now, this is also with a fan blowing on them HARD all day AND night, we'll see how it goes since this is my first time doing like this, I always did like you and cfl'd & windowsilled them until I read Julians thread, but as long as I can keep 'em from drying out it should be good, and they won't be all pussy about the sun Today I'm going to try to rig the t8's so I can have them on the plants from the other angle of the sun, it sucks because I also have to move them around to different spots of the yard.
But yeah, I don't know your situation but I would try to get them in full sun asap, but watch them like a HAWK, you probably will have to pull them into shade, then sun & watch again etc etc because you can kill underlit seedlings FAST
