Answers
1) The submucosa. Sutures can go full thickness, but the colon easily separates into two layers, which can be sutured separately (serosa and muscularis; submucosa and mucosa).
2) A synthetic, absorbable, monofilament suture. A blunt needle.
3) A simple, appositioning, continuous suture is now recommended (one or two layers). An inverting or everting suture pattern is unacceptable. Simple interrupted sutures are not recommended anymore.
