Gonna move my answer which I made to the pre-sales area here...
Anna,
Once you find the right template file in JomSocial that you want to modify, you'd simply add the following tags:
{JFBCComments} - Will add the comment box
{JFBCLike} - Facebook Like
{SCTwitterShare} - Twitter Share button
{SCGooglePlusOne} - Google +1 button
{JLinkedShare} - LinkedIn Share button
There's a ton of other tags available, like a "Login with Facebook" tag {JFBCLogin} that can be used to let users login on that page (makes it easier to attend the event) as well. For a full list of our available tags, see:

Hope that helps, but if you have other questions, just let us know!
Thanks,
Alex
