What are all of these extra hotfixes for?

While working on building an updated Windows 7 SP1 disc, I found a bunch of hotfixes I had which weren't part of my slipstream but were also not missing as an update while querying Windows Update post-install.

Does this mean that all of these updates have been included elsewhere in a rollup I've already installed?

Hotfixes generally are to be used in an as-needed basis and not used just because. You should research each KB and determine if they are needed for your deployment scenarios.

While trying to filter through what I do have, is there a way that I can determine if a particular hotfix already exists in a rollup I've already installed?

You can check file versions.
