Help! How to prepare for baby number three?

I am frantically seeking for guidance, information, advice, reference materials, etc. that addresses parenting under any of the following "situations and/or circumstances": raising three children under three years old, how to prepare a two year old and a nine month old for another baby, how to balance our growing family, ideas/samples of daily schedules & routines, and activities/games/toys/outings that will engage a toddler plus Irish twins, etc. etc.!!
I am a stay at home mom (with an M.Ed. in Special Education) with a two year old son (born 06/07) and a daughter that's almost ten months old (born 11/08); I am currently 33 weeks pregnant with our second baby girl!! I'd love to connect and share stories with other moms with this situation!
Any suggestions appreciated! Thanks so much!
