Apparently my slave cylinder is going out considering the car wont go into 1st unless I pump the clutch pedal. Also if I have my foot all the way to the floor and the car in gear at a light it pulls forward a little so I have to hold the brake. What all needs to be done to swap this setup out?

I'm purchasing the whole combo already bleed. Does the car need to be left in a certain gear or neutral? also anyone know off hand what tools are needed for this? I was told there are 2 10mm bolts that hold the slave to the side of the transmission.
