Try "icmp and ip.addr eq 10.10.208.211" to find packets to/from that IP 
that are ICMP -and- packets that have ICMP packets containing traffic 
to/from that IP in the ICMP payload.

No, because it is handed by the IP dissector and then TCP/UDP 
dissectors.

Not easily.  You could add "!frame.number == #" to the display filter 
or mark certain packets and save only the marked ones or save ranges of 
packets in the save dialog.
