nterpretatin #1:
What factors determine the charge pump current?
This is determined by the transistors inside the PLL chip. When designing a PLL, if the charge pump current is too high, then this will take up too much die area. However, if the charge pump current is too low, then phase noise will be degraded.

Assuming the filter is optimized, the charge pump current has no impact on lock time. There are a few smaller order effects though.Large charge pump currents lead to larger capacitors, that sometimes decrease lock time due to poor dielectric properties. If the loop filter is not changed, increasing the charge pump current increases the loop bandwidth and can therefore increase the lock time, assuming the filter is kept stable ( with a fastlock resistor ).
