Don't recall the hose being in the way but can help with Q#1:
If you follow the cable under the throttle body you will notice a crimp on the end of the cable. Back along the throttle cable you can flip the plate next to the big spring or under the throttle body and unhook/loosen the cable.
Alternatively, if you are still unsure how to proceed, have someone slowly press on the accelerator pedal (with the engine off) and watch how the cable moves the throttle body. In the open position, grab the cable and unhook the crimped end underneath.
Warning: be careful with the plastic adjustment parts, (thumb screw) the can easily break.
