Screwdrivers can be used (and I've been as guilty of this as the next guy) but a 'real' set of tire irons is a better choice. The sharp edges on the 'drivers can mar the soft aluminum pretty easily. Or pick up a set of 'rim protectors'. As to going as high as 70 psi (!!!???) to seat the bead, I'd be very careful. At that pressure, when that tire slams home you may risk breaking the rim and death/injury is a possibility. Clean and/or relube until it seats at a reasonable pressure (> 50 psi). Wacking the tire with a large rubber hammer has helped seat the bead also.
Being the cheapskate that I am, I've always mounted my own bike tires, but it is a chore. A 'third hand' can be very handy (SWMBO if I'm desperate), but it's doable by yourself...
