Power would be V*V/R or slightly over 0.25W. I would use an 0.5 or 1W resistor for the purpose, and expect it to get quite warm. Exact resistor value won't be too critical - if I had a 10 ohm resistor handy it'd just take a little longer to charge.

Webachieve the desired start-up time. Increasing the bootstrap resistor values will increase the time constant leading to slower start-up time.
