Get Comments

I am trying to display comments on a certain page of my site is there a function/way to pull comments like a get comments tag or something? I searched codex and here but couldn’t find what I was looking for.

I want to have users put in comments for an interactive section like Caption this! (photo) and then have it display their comments on that page once they are approved but i am trying to also use a custom comment form that will have:

Name
Email
What do you think ? is sayin

So then that gets into me needing another whole comments form but I don’t want the form sent to my email I want it to go onto the site so all i have to do is approve the comments via the dashboard. I have seen some other forms but they are contact forms and that is not what I want.

Help on either issue or whatever is easiest will be appreciated. Thanks!
