Changing fields in custom post types

I have two questions:

1. I have setup 4 custom post types when we first installed the plugin last year but now I can’t seem to recall how we added the last bit of info on the page.

We have a mandatory checkbox that says ” I agree to the terms and conditions”
and right below that we have a box that says “review your membership profile”.

Am I correct in thinking that we have to go back and edit the language file or
is it somewhere else?

2. I have disabled most of the fields on this new CPT but there are quite a few
that are not on the list, that are able to be edited or activated.

For example, we do not want see the map, business owner, latitude, longitude, etc.

This CPT will only be used for our members to see a few fields regarding a clients “service Request” and we don’t need very many fields.

Will our programmer be able edit or deactivate these fields or will it cause
problems with the site?

As always, thanks for your help.
