I've read this and your other questions regarding OCS, and someone from the team will reply to each in turn with specific responses as necessary. I would suggest that if you are currently testing out OCS you may want to wait for OCS 2.1, which will be released by the end of the month. It has many new features, including some you are looking for. If you would like to get a sneak peek for testing purposes, you can checkout OCS from CVS:
cvs -d :pserver:firstname.lastname@example.org:/cvs login
cvs -d :pserver:email@example.com:/cvs co ocs2
You can add more items under About the Conference by visiting Conference Management --> Website Management --> Step 1.6 (1.7 in OCS 2.1). Anything you add here will appear in the About page, under Policies. You can add multiple items here if you want.
In OCS 2.1, the Registration information page has been expanded to "Registration and Accommodation." You can view the following bug report and patch: http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=2920
