When you say a clutch kit, did that include new fiber plates/rings? If yes, then did you soak them over night in oil? When you tried the clutch lever with the cover off, was the clutch fully assembled, spring and all? Less important, what weight oil did you fill with?

Hard or difficult shifting is normally caused by the clutch plates not fully disengaging. The plates are sticking or dragging and the friction is preventing easy shifting. The new clutch pack could be too thick, or the clutch slave may not be giving full travel. I would bleed the clutch hydraulics. This allows you flush out any old fluid and remove any air that might be in the system. When trouble shooting I like to do the easy/simple stuff first.

Can you roll the bike around in gear with the clutch lever pulled in?

No, that is an internal part along with the o-ring and it will not affect getting air into the hydraulics. Report back after bleeding the hydraulics.
