Can someone pls help me?

I need to go to Pusat Komersial South Gate tomorrow morning at 9 am from Klang.

I intend to take a KTM to KL Sentral, then change to Star line to go to Chan Sow Lin (Is this the correct station??).

But I think I must change to Putra to go to Masjid Jemek first, is that so ???

Thanks a lot.. yeah !!!
