    A good pair of hedge shears or a power hedge trimmer are the best tools for trimming hedges. Here is more information:

    It sounds like your shrub is a barberry. Here is more information about these plants:

    Your plant may still be able to grow back next spring. For the winter, you could try mulching over the area where the roots are with dry leaves as in this technique:

    There are some barrier products on the market that can be placed into the ground to keep roots from invading areas. Since you all ready have the roots invading into the surrounding area, I'm no sure how successful this type of system would work for you and the work to dig and install can be extensive.
    There is little to be done other then removing the troublesome shrubs and replanting with something more well behaved.

    This is a leaf spot disease that could be bacterial or fungus.
    Treatment will vary for both with the exception of clean up and removal of diseased plant material.
    This link has more information.

    I am not sure what shrub you have, but there is a shrub called Texas sage (not a true sage) that sounds similar:
    http://www.south-florida-plant-guide.com/texas-sage.html

    If that's what you have, a hard pruning as described in the article is recommended for the problem you describe. Basically, you'll cut back some of the branches to near the base but leave others longer so it still has some leaves.

    If not, you can try a hard pruning anyway (cutting the plant most of the way back) and see if it grows back in a better-looking state.
