Wait until you have enough money and order everything together. There is no point in installing the clutch now and then the CSC later. It would double your time or labor cost.
The pressure plate is included with the clutch. When you order the HD CSC, Zspeed will include the appropriate throwout bearing with the CSC.
The other item you might need is a pilot bushing. Most of the time, the pilot bushing should be fine. But since you have the tranny out, might as well replace this cheap ($5) part just to be safe.
If youre are doing the clutch install yourself, you will also need the alignment tool. Judging from the pictures on zspeed's website, these items are included.
