Regarding this, where the saddle is mounted on lathe?

Explanation: Saddle is H shaped casting and has v guide grooves and flat grooves. Saddle is mounted on the spindle.

Which lathe component slides along the ways and supports the cross slide and cutting tool?

The tailstock is usually a casting that slides along the ways. A locking mechanism called the clamp bolt or binding lever secures it to the ways and prevents it from moving. The tailstock holds a lathe center in its ram for turning or facing.
