Your front lawn has what appears to be snow mold or chinch bugs. To check, at the edge of the dead spot take a sample of the turf including the root zone, place in a pail of water. If the bugs float up to the top, there is your answer. You will need to apply a insecticide to deal with that. If not, then you need to apply a fungicide, and topdress and overseed the affected areas. To really green it up, rent a de-thatcher and go over it with that. As that process can be done very quickly, go in with a neighbour or two on the rental to cut costs.
As for the driveway, round up. Now banned for public use, so the alternate is a weedwhip on an angle weekly.
