I have the graco duo glider that I purchased at USA Baby (I reccomend there because its the better version then babies r us plus you get to pick your pattern). I love it. There is some more expensive strollers out there, but this is easy to push, colapse, and its not that heavy for a double stroller. My daughter was 5 mos. old when I found out I was preggo with my son. They are 14 mos apart to the day. I then continued and had 3 in 2 1/2 years. I was so scared too when I found out I was preggo agian. But honestly it took me about a week before I got into the routine, and now that they are 2 and 3 its great. You are endlessly in diapers, but now I can't imagine having them further apart, they are so close. When he falls she is the first one there saying "its ok sisters here, do you need a kiss?" giving him a hug the whole time. I think they truely have a very special bond because they are so close. It wont be as bad as you are thinking! I just remember being so scared! I do have some great tricks for doing things x2 (well x3 now) if you need. Let me know!
