yes.  You can also protect the switch's IP by setting up a dedicated
management VLAN.  All decent switches support this.

No.  When you have VLAN's, it's the same as having a bunch of
individual switches.  Different broadcast domains, and different IP
subnets on each.  If there isn't anything to route between them, your
network is dead.

Depending on what kind of switch, you may be able to put all hosts in
a single VLAN and prevent them from talking to each other (google
PVLAN, and/or check out the docs for your switch).
