HERE, HAVE TROY AND ABED.

YEEEEEEEEEEEY. I have two commentaries left on the first season, but when I'm done I'll lend you the DVDs so you can watch it (I've already watch season one three times, including with commentaries, so I'm banning myself from watching it again for awhile so I don't get burnout).

This is kind of a spoiler (but not a huge one, since it happens pretty early in season three) but Troy, Abed, and Annie all live together, which will make these answers make more sense to you.

who is the big spoon/little spoon 70/30 towards Troy being the big spoon, as he's more a cuddler than Abed is. Sometimes, though, Troy will ask Abed to be the big spoon.
what is their favorite non-sexual activity Playing pretend in their Dreamatorium and watching movies together.
who uses all the hot water in the morning They're both pretty quick in the shower, actually. Troy hates longs showers since they get lonely, and Abed figures there' much more interesting things to do than shower. Once, though, it was both of them, since they tried to have sex in the shower since it looked hot in the movies. However, it was too slippery, they got all pruney which ruined any sort of sexiness, and the water bill they got was not pretty.
what they order from take out Normally it's just the typical stuff, like lo mein, curry, or pizza, but occasionally they'll decide to order the weirdest sounding thing on the menu and get Annie to try it with them too, just for fun. Abed's the one whose usually okay with whatever the food is, and Troy's the one who is more picky.
what is the most trivial thing they fight over Most of their fights are over trivial things, and are pretty friendly. However, they probably wouldn't agree with me that Han Solo vs. Indiana Jones is trivial (On that one, Troy was for Han and Abed for Indy, so they brought in Annie to be a tiebreaker. With a secretive smile at Abed, she answered, "Han.")
who does most of the cleaning Annie, as we've seen. xD Though she will force Troy and Abed to help her, occasionally.
what has a season pass in their DVR Abed obviously. So many TV shows, so little time. The ones he watches live are Cougar Town (Troy won't watch it, but he managed to make Annie a fan) and Inspector Spacetime (which is also one of Troy's favorite shows, so they love to watch it together).
who controls the netflix queue Abed, as his knowledge of movies and TV is much larger than Troy's.
who calls up the super/landlord when the heat’s not working Annie, as she doesn't have anyone to snuggle closer to and share body heat with.
who steals the blankets Abed, since he gets cold easier. Troy usually just gets closer to Abed instead of taking them back.
who leaves their stuff around Both, but different stuff. Abed's the type to be careful about his belongings (except for a rather ill-fated Batman DVD), but leaves his food around since he figures he's just going to go back to it. Troy leaves his belonging lying about, but is careful about food since he knows that it attracts mice and other sort of creatures that scare him
who remembers to buy the milk Annie. Troy will throw out the old one and forget to buy it again, and Abed will see that the milk's gone bad, but just leave it in the fridge and put juice in his cereal. Eventually someone remembers to buy milk, but it's pretty sporadic until Annie moves in with them.

who remembers anniversaries Annie was the once who actually remembered their first one year anniversary. Troy actually forgot, and Abed decided to forget to invoke Forgetten Anniversary tropes, thinking Troy would remember. Annie, ever the romantic, is freaked out that they aren't doing anything for it, so when she asks about it, they realize they didn't remember so they make last minute plans to go to dinner and a movie. The next year, they both remember, but Abed pretends to forget so they can act out the Forgotten Anniversary tropes in a more conventional way. After that, it's whoever can remember that year, occasionally both of them, but someone always remembers and reminds the other about a week before. Neither is the sort to get angry over the other forgetting an anniversary, excepting for that second one since that was Troy's role.
