In reply to climberjamie:
You probably want to focus on hip flexibility, so:
Utthita Parsvakonasana (Extended Side Angle Pose)
Virabhadrasana 1 & 2 (Warrior Poses)
Ardha Baddha Padma Paschimottanasana (Half-Bound Lotus Seated Forward Bend)
Baddha Konasana (Bound Angle Pose)
Janu Sirsasana (Head-to-Knee Pose)
Ananda Balasana (Joyful Baby Pose)
Eka Pada Rajakapotasana (One-legged King Pigeon Pose)
Ardha Matsyendrasana (Half Lord of the Fishes Pose)
Prasarita Padottanasana (Wide-Legged Forward Bend)
Plus some basic stuff for the back & shoulders:
Adho Mukha Svanasana (Downward-Facing Dog)
Bhujangasana (Cobra Pose)
Chaturanga Dandasana (Four-Limbed Staff Pose)

Remember that the same name is sometimes used to refer to different poses, and that the spelling of the Sanskrit is a bit variable!
