Actually it's easy. You use a hot air re-work station. Basically a hair drier with a 1/8th inch diameter nozzle. Hold the little part in place with a wood tooth pick and aim the hot air generally at the part. The solder on the part and the PCB melt, release the toothpick and surface tension

Typically 0.1 bypass caps REALLY to have to be physically close to the load they are bypassing. Within a few millimeters. Cut the leads short and bridge the power pins with the cap. Placing a larger cap farther away can't cause any harm but it is not going to do the same job. Reason: The real
