If you use ospho, you don't have to do a lot of work with the wire wheel. Again, the ospho turns the rust into a primer.
The biggest thing is to make sure you've removed any thick rust scale, as this can flake off after you've painted. Beating with a 2 lb hammer will pretty much knock most of the scale away. A chipping hammer will work good on smaller parts, or persistent rust scale.
