Scratch that, I just re-checked your pics. It should be:
a stereo phono cable
a stereo phono to stereo mini jack adapter.
2 x XLR to jack plug leads
2 x jack to jack (guitar) leads
1 x mono jack to mini stereo jack adapter (has 2 mono inputs, 1 stereo out)
1 x mic lead to connect your microphone
1 guitar lead (if you play guitar or another instrument you plan to DI (Direct Injection) record (ie not via an amp and mic)
As your amp can also be midi controlled you should also see if you have a midi in/out (if not buy a USB/midi adapter) and buy 2 midi leads to connect the midi input on the amp to the midi out on your PC, and the midi output on the amp to the midi input on your PC. You can then control your amp from a software sequencer (like Cakewalk Sonar, Cubase or a cheaper alternative) and I believe record parameters made as you adjust dials and settings on the amp directly.
