How far is the distance between sultan salahuddin abdul aziz mosque (blue mosque )and pewter factory and? batu?

batu caves as I am planning to catch the kelana jaya line from kl Sentral to batu caves (what is the nearest station? Is terminal Putra/Gombak last station on the line ?) Get down at the station catch a taxi willing to wait for me at 3 places , go to batu caves , from there to Selangor pewter factory , then go to the blue mosque and then catch the nearest train station back to KL Sentral. I believe all 3 are in Selangor state,.Thx for helping a confused guy
