Yes, there is a battle at the Moonpool in the Warriors series. The Moonpool is a sacred place where the Clans come to share dreams with StarClan, and battles have taken place there when tensions between the Clans escalate.
Yes, Breezepelt attempted to kill Hollyleaf in the Warriors series. He was manipulated by Dark Forest cats and held a grudge against the ThunderClan warrior because of their past conflicts.
Yes, Jayfeather and Dovewing hear Mistystar going to the moonpool. It is unknown how Leopardstar lost her last life but is suspected of being from old age. I thought it was Greencough or something! They didn't really specify, but they did say old age or an illness.
It is the stick that Rock used to count the lives of cats that went into the caves. It's special to him because he shared dreams with Rock.

Jayfeather discovers that the Tribe of Rushing Water used to live at the lake. But a newly appointed sharpclaw name Jay's Wing chose for the ancinets to leave the lake. Then later in time the Clans started to exist. When Jayfeather walks the path to the Moonpool, he can hear the whispering of cats.
