Regarding hole sizes. As someone who spend his days repairing 2 way radios I can tell you that, parts that are accessible to the outside world are the most common thing to break. Volume controls, switches, and jacks. Provide LOTS of clearance around the leads and pins of those and other multi-leaded parts. If possible, use parts that have protrusions that interlock with the board so that external force is not applied to the solder connections. When you or someone else has to repair that board you will be glad you did. It is very frustrating when some bonehead lays out a board with a thou or 2 of clearance around around the pins of a part and also forgets to include thermal relief for the ground and power plane connections. If you have the room, allow for it. The added cost of the solder is irrelevent. Anyone that does repairs on a daily basis knows what I am talking about.
