How to open a file in a list of files in Vim?

I'd say with -p for tabs

vim -p `cat yourlistoffiles`

You can use quickfix mode, as following

:set errorformat=%f
:cf myfilelist

at this point you can use the normal quickfix shortcuts to go through your files, :cn for the next file, :cp for the previous one and :cr to go to the first again.

EDIT:

oh, if you want to read the list from the current buffer, use :cb instead of :cf in in the instructions above
