Sorry, I don't have quick solutions for what I see in your files.
There are many select statements in state: locked ... Your biggest problem seems to be the storage engine - you're using MyISAM.
You should consider switching to InnoDB, but you should test the migration thoroughly. And you should upgrade to a newer version, 5.1 is may too old.
I suppose your best bet now is to activate the slow log (if I recall correctly, it's dynamic in 5.1) and try to tune your queries, to minimize the locking issue.
By the way, why you're using 2G for the InnoDB buffer pool and only 128M for your MyISAM key buffer? Do you have InnoDB tables
(not mentioned in the uploaded files)?

mysql_convert_table_format
MYSQL_CONVERT_TAB(1) MySQL Database System MYSQL_CONVERT_TAB(1)
NAME
mysql_convert_table_format - convert tables to use a given storage engine
SYNOPSIS
mysql_convert_table_format [options] db_name
DESCRIPTION
mysql_convert_table_format converts the tables in a database to use a particular storage engine (MyISAM by default).
mysql_convert_table_format is written in Perl and requires that the DBI and DBD::mysql Perl modules be installed (see Section 2.13, "Perl
Installation Notes").
Invoke mysql_convert_table_format like this:
shell> mysql_convert_table_format [options]db_name
The db_name argument indicates the database containing the tables to be converted.
mysql_convert_table_format supports the options described in the following list.
o --help
Display a help message and exit.
o --force
Continue even if errors occur.
o --host=host_name
Connect to the MySQL server on the given host.
o --password=password
The password to use when connecting to the server. Note that the password value is not optional for this option, unlike for other MySQL
programs.
Specifying a password on the command line should be considered insecure. See Section 6.1.2.1, "End-User Guidelines for Password
Security". You can use an option file to avoid giving the password on the command line.
o --port=port_num
The TCP/IP port number to use for the connection.
o --socket=path
For connections to localhost, the Unix socket file to use.
o --type=engine_name
Specify the storage engine that the tables should be converted to use. The default is MyISAM if this option is not given.
o --user=user_name
The MySQL user name to use when connecting to the server.
o --verbose
Verbose mode. Print more information about what the program does.
o --version
Display version information and exit.
