I am looking for recommendations for setting up a MySQL server on a server with 4gb memory.  Below are the ISAM setting from a server a few years old, and I suspect they are default settings and not tuned at all to the server it's running on.  
Question: My current mysqld process is using 1.8 percent memory.  Should that be configured to use 50% or more on a dedicated MySQL server ?

key_buffer                              = 16M
max_allowed_packet                      = 1M
table_cache                             = 64
sort_buffer_size                        = 512K
net_buffer_length                       = 8K
read_buffer_size                        = 256K
read_rnd_buffer_size            = 512K
myisam_sort_buffer_size         = 8M
