In general, you should avoid use of the prefix ptm unless you are fully aware of the consequences, as doing this may interfere with the many other support files using this prefix. And, if you are trying to fit these two special faces into an existing package, you don't need to build everything from scratch, and the current TeXLive packages that offer Times support have in most cases already provided their own support files for their versions of small caps, which are supposed to be metrically equivalent to Adobe's. So, it would help to know which package your are trying to insert these into, as it may then be possible to modify the map file and the fd files to point to your own modifications. You may even be able to avoid fontinst in favor of afm2tfm, which is much less involved.

To answer some of your other questions, tex searches for support files in texmf branches in the following order (in TL2014).

1. Current folder.
2. ~/Library/texlive/2014/texmf-var
3. ~/Library/texmf
4. /usr/local/texlive/texmf-local
5. /usr/local/2014/texmf-dist.

So, anything you install in 3. will take priority over the system files 4. and 5.

So, it is important to know which Times package you will start with.
