Hi A.:
Congrats on your twin pregnancy! Your nearest local twins group is Twins by the Bay http://www.twinsbythebay.org - they have both daytime and evening support groups for new and expectant parents as well as email forums so there's plenty of places for you to ask all those questions and connect up with other expectant parents as well as more 'seasoned' ones :-). Meanwhile, keep drinking lots of water and have plenty of healthy snacks on hand (I used to keep a bag of potatoes in my desk drawer at work and would microwave one and top with a drizzle of salad dressing when I needed something a bit more substantial than fruit and crackers!) Plenty of moms deliver their twins vaginally and full term (speaking from experience - mine were induced at 41 weeks and my OB delivered them vaginally even though baby B was breech)
Good luck!
