Find a big vacant parking lot and just practice heaps. When my dad was teaching me to drive I'd spend an hour on sundays just going in circles around the lot.
It really is just a balancing act between the throttle and the clutch.
find somewhere quite and practice easing out the clutch slowly without touching the throttle until you hear the engine revs starting to drop. This is the "friction point" where the car will start to move if it has enough throttle.
once you have a feel for the friction point start gently applying the throttle as you reach the friction point and then keep easing out the clutch as the car starts to move.
If your starting on a hill then you are going to need more throttle to get you moving but with practice you'll be able to hold the car in one spot on a hill without touching the breaks. (this will wear the clutch over time)
reverse is pretty much the same technique, so just practice in first for a while so your not worrying about whats behind you.
for advanced driving try heading into a hard corner full tilt in third, instead of breaking slam it back into second and then breaking. This should cause the rear wheels to break traction and slide you around the corner. when the car is pointing in the direction you want to go apply some throttle and give the bird to the car that is abusing you for nearly wiping them out.
