Here are the settings I am using now.

I would like to be able to dumb it down a little more. Can you
suggest what settings are best for this.

By "simplify the position", I assume you mean "trade pieces". This can
be accomplished by setting, for example, the "My Queen" value to be
slightly lower than the "Opponent Queen" value in the personality
settings. This will cause the personality to trade pieces more often,
but still only when it would otherwise be relatively equal to keep them
on the board.

Secondly, you could decrease the "Contempt for Draw" setting. This is a
bit more subtle, but it will cause the personality (as best as it can
based on its other settings) to be more accepting of a position that is
likely to lead to a draw (which includes trading pieces). However, it
might also tend to cause the personality to lock up the position or
shoot for a quick 3-fold draw even when it has an advantage.

There are several pre-defined opponents that will provide a good
challenge and play fully believable chess.

In increasing strength, I would try these (ratings as displayed on my
P4-3.0):

Joey (1125)
Kris (1145)
Josh - Age 6 (1200)
Griffin (1282)
Lacey "The Dreaded" (1308)
iah (1320)
Josh - Age 7 (1365)
Sunny (1444)
Trent (1463)
Charles (1472)
Ginger (1506)

All of the others in that range have quirks that will either make them
defeat themselves if you are patient enough, or are relatively easy to
exploit once you know what they are.

Enjoy!

When playing with a human that has about the same rating I have, the
moves are predictable. Not too many moves seem unusual.

When playing a computer dumb enough for me to beat doesn't have the
same feel. Some moves seem too strong while some moves seem too dumb.
Most of the players that play at my level choose to simplify the
position. This doesn't seem to happen when playing computers.

I can't really define it but playing computer chess is either too easy
or too hard.

Is there a setting that causes the computer to simplify the position?
Then again, not too simple.

You could try to lower the max search depth by one. That should make it
play slightly worse (and will also make it play slightly faster).

As a beginning guideline, Terry, you might be interested in a personality I
made. It's identical to the Chessmaster 9000 personality but Maximum Search
Depth is set to 9. (Selective Search is 9.) It averages 15 seconds per
move. I played it against other CM9k personalities, and it seems to play at
about 2600. In other words, it lost to the other grandmasters but beat
everybody below the grandmaster level.

Not bloody likely. I play around 1200. Every game I have beat so far
the Chessmaster said it was good for me taking advantage of a blunder.

I really would like to be able to play against a pretty weak opponent,
but not one stupid enough to leave pieces that can be taken without
being defended once.

I can beat this player but I am not sure what settings I should
increase.

I am not really sure what selective search does.

I also have no clue if increasing the transposition Table makes the
game harder or just gives it more performance. It plays plenty fast
now.
