Stable cell transfection

A couple o' questions :

1. Is it absolutely necessary to linearise the plasmid before
transfection? My cell lines cannot support plasmid replication, so
integration is required.

2. How long after transfection should one wait before adding antibiotic to
the culture medium? I'm using hygromycin B, and transfecting by
One of the cell lines is adherent (EL4), the other grows in suspension (P815).

Any advice welcome
