    That's all you need for starters. If you need thinner shims, check the Shim Club

    75 is a bit low for a cold compression reading.

    Make sure you have the plugs wires on nthe correct cylinders

    Doing valve adjustments on a rocker arm engine is much easier IMO. Got a set of feeler gauges? just check them first for clearance.
    Reassembling the top end without at least breaking the glaze (honing) or replacing the rings is probably a large part of your problem.
