mysqltuner.pl Optimise help needed.

Hi, the past two weeks my server started to run on high server load and again I need to look at all the thingies that can be the cause thereof... Please help...

I notice that the slow queries is not problem!?!?!? ([OK] Slow queries: 0% (11K/31M))
But found that the slow query log grew to 10Mb in 4 days...?
Also why would it log something like:
# Time: 120820 12:59:54
# User
# Query_time: 0 Lock_time: 0 Rows_sent: 27 Rows_examined: 54
use thedb;
SELECT * FROM bdircats ORDER BY cname ASC;

What am I doing wrong?

mysqltuner.pl looks as follow and below it is contents of my.cnf :

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    Reduce or eliminate persistent connections to reduce connection usage
    Adjust your join queries to always utilize indexes
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries without LIMIT clauses
    Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
    max_connections (> 200)
    wait_timeout (< 1800)
    interactive_timeout (< 28800)
    query_cache_size (> 128M)
    join_buffer_size (> 256.0K, or always use indexes with joins)
    tmp_table_size (> 64M)
    max_heap_table_size (> 64M)
    table_cache (> 1024)

Code:

[mysqld]
skip-innodb
max_connections = 200
key_buffer_size = 220M
myisam_sort_buffer_size = 64M
join_buffer_size = 256K
read_buffer_size = 256K
sort_buffer_size = 256K
table_cache = 1024
thread_cache_size = 16
wait_timeout = 1800
max_allowed_packet = 16M
query_cache_limit = 1M
query_cache_size = 128M
query_cache_type = 1
log-queries-not-using-indexes
log-slow-queries=/var/lib/mysql/slow.log
tmp_table_size = 64M
max_heap_table_size = 64M

[mysqld_safe]

[mysqldump]

[myisamchk]
key_buffer_size = 96M

Thanks for the help...
