The coolant level goes up because it expands when it heats up. The expanding coolant overflows into the overflow bottle. When the engine stops and the coolant cools down, it will get sucked back into the radiator/rest of the cooling system. This is normal.

 

You need to adjust the clutch "engagement" via the clutch pedal or master cylinder under the dash (ie screw behind pedal). Most likely your experiencing "clutch drag".. One way to test is put it in first gear, and rev to 7k rpm.. Be careful when doing this. If your car rolls forward when doing so, your clutch is dragging.

Link to all your transmission / clutch issues. Also how to adjust clutch properly.

Also I don't think HP is a good way to measure if the clutch is up to the task. Foot pounds/ FT-LBs is a more accurate way to determine a clutch, for proper clamp loads specifications. Post your torque goals and we can better help you decide on the clutch for you.
