My girls are 8 months old, 6 months adjusted, and they sleep in their own beds in the same room. They always start the night in their cribs, but often we will co-sleep with one and switch them out as they wake. Until they were about 4 months old, they were co-bedded, but started waking each other up with kicking.
Routine isn't very firm yet, but we've been working on it more and more. Around 7:00 we start bathtime and pajamas. We turn down all the lights in the house and tone down the noise level as much as we can with a toddler! Cluster feeding starts and I nurse one baby while my husband holds the other and puts our toddler to bed.
When the baby I am nusing gets droopy eyed, I swaddle her and attempt to lay her down. If she cries, we rock for a bit and if that doesn't work we nurse again. I've tried really hard not to set-up the suck to sleep association. I get the second baby from my husband and repeat the whole method. We play a Celtic lullaby CD in their room all night and keep the temperature warm.
When one wakes, she comes to bed to nurse and co-sleeps until the other wakes. My husband is great about getting up and switching them out.
We tried co-sleeping with our first daughter for almost a year. I was miserable and she was waking many (6+) times per night up until she was a year old and we chose to slowly cut out night nursings. I'll admit to not even wanting to attempt to co-sleep with the twins full time.
For naps, I do pretty much the same thing as night routine. They are swaddled and we nurse until they are super drowsy.
Currently both twins are in bed before 8:00 p.m. and Morgan wakes once and wakes for the day at 7:00 a.m. and Meagan wakes 1-3 times and is awake for the day at 6:30 a.m. On a rare day, they will both sleep in until 8:00 a.m.
Their naps range between two 30ish minute long catnaps, one around 10:00 a.m. and another around 4:00 p.m. to one long 2-3 hour nap starting at 11:00 a.m.
With a toddler that still wakes up 3-4 times per night I think we've lucked out with these kiddos and sleeping!
Here's hoping you get some sleep soon, Mama. I know it sucks to be without it and have so much on your plate.
