This was a life saver for the first 6 months http://www.amazon.com/Baby-Trend-Dou...8669167&sr=1-3
We chose to go with a side by side. As the kids got older it has saved us the argument of who gets to go in front and it also saved us from the one in the back constantly kicking the one in the front. lol If you haven't seen this one try to check it out. http://www.amazon.com/Baby-Jogger-Do...8669285&sr=1-1
The Chicco's are nice if you need the room. We used the snugfit.
I would suggest separate cribs. Oftentimes you have one who is a restless sleeper and disturbs the other and in theory it ups the risk of SIDS. However, I know a ton of moms whose twins slept together up until about 3 months.
And these are bouncers http://www.amazon.com/b?ie=UTF8&node=166851011.
Also, invest in a good swing. Our two didn't love the bouncer but they LOVED the swings.
