I'm planning to practice my fundamental flight skills around the KBNG (Banning) area.

1) When flying traffic patterns on KBNG only, should I also establish contact with SoCal App (next to announcing my intentions on CTAF) – since I would by flying within the 20 nm range of many neighbouring Charlie's?
2) And if I instead decided to depart from KBNG and practice flight manoeuvres in the area 10 nm south of KBNG (with no intentions to transition through Charlies), should I then contact SoCal to let them know what I'm up to?
3) I wondered the same thing when visiting KIZA (Santa Ynez) with respect to KSBA's (Santa Barbara) Charlie airspace. Should I contact KSBA Approach when I'm inbound from the North and plan to just land on KIZA? If so, what do I say to approach?
