Installshield from Macrovision/Need to know what it is

The install shield update manager is used/installed with some software (Sonic, Corel....). .  The related startup items you mention refer to its automatic update features (i.e. it looks for updates for the apps it is monitoring), and are generally not required because the kind of apps it monitors in my experience do not offer updates at all frequently. For example Roxio Easy Media Creator suite 8 (which installed the update manager oh my system) had one update in a year; Corel Paintshop pro X which it also manages has had 3. So it is bettter to check manually from time to time.

For ISUSPM.exe it states

InstallShield Update Service related; Automatically searches for and performs any updates to the software. Not required.

For issch.exe it states

InstallShield Update Service Scheduler; automatically searches for and performs any updates to the software so you’re always working with the most current version. Not required.

You can use the control panel icon to check for updates manually for the software it is monitoring (you can see what they are by double clicking on the icon and clicking settings). Or you can use the check for updates feature in each app. If you uninstall the update manager, the manual check for updates in the apps that use it may not function.

However, if you want to uninstall the instalshield update manager, you need to download the uninstaller from:

as you found out, it is not listed separately in add/remove.
