SRC Midori
SRC uses Midori to do the web browsing.

SRC ISOMaster/Xfburn
ISO Master allows you to create ISO files and/or remaster SRC.

Xfburn allows you to burn crud to a CD/DVD.

SRC GTK+ lshw
This thing is a graphical GTK+ frontend for the lshw command.
lshw lists the hardware in the system, and also has subcommands for weeding out stuff from the list.

SRC TestDisk
Testdisk is a command-line based utility that can be used to recover data from partitions that have been damaged due to software problems and a few hardware problems.
If your drive doesn’t read anything, good luck getting your data back as this is totally useless for that purpose.

SRC Settings
Fairly pedestrian XFCE settings thingy.

SRC Shutdown
Shutting down SystemRescueCD.

Conclusion:
While it is simple, SystemRescueCD does not need to be feature-packed to be useful for it's purpose. I, as of the writing of this conclusion (March 2013), am using it full-time to repair machines which have damaged partition tables and as a basic recovery tool. Not big on USB flash drives however.
