How to see the hostname and the URI requested for?

edit

Where in the capture will I see the hostname(i.e. domain name) and the URI which has been requested for?

The host name will probably be in the HTTP request, with "Host:", although for HTTP 1.0 it might only appear in the IP header of the packet(s) of the request (in which case it'll appear only if Wireshark 1) is resolving IP addresses to names and 2) can resolve that IP address).

The URI should also appear in the request.

For an SSL request will this be encrypted?

Yes.
