I find with multiple generals that I just keep them all in the primary army. Then they just stay there. Although I really have not fought any battles with over 20 units so I haven't had to combine armies like that yet. If I do I'll likely transfer the generals into the main army that attacks.
Haven't noticed the suicidal daimyo problem yet. It seems the enemy throws the leader in once most everything else is committed. I almost always get the leader killed message in the last bit of the battle.
