It should be safe to follow these recommendations

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10 sec.
You have 234 out of 14041255 that take longer than 10 sec. to complete
Your long_query_time may be too high, I typically set this under 5 sec.
BINARY UPDATE LOG
The binary update log is NOT enabled.
You will not be able to do point in time recovery
See http://dev.mysql.com/doc/refman/5.0/en/point-in-time-recovery.html
WORKER THREADS
Current thread_cache_size = 384
Current threads_cached = 175
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine
MAX CONNECTIONS
Current max_connections = 1000
Current threads_connected = 5
Historic max_used_connections = 180
The number of used connections is 18% of the configured maximum.
Your max_connections variable seems to be fine.
MEMORY USAGE
Max Memory Ever Allocated : 5 G
Configured Max Per-thread Buffers : 27 G
Configured Max Global Buffers : 650 M
Configured Max Memory Limit : 28 G
Physical Memory : 7.61 G
Max memory limit exceeds 90% of physical memory
KEY BUFFER
Current MyISAM index space = 111 M
Current key_buffer_size = 384 M
Key cache miss rate is 1 : 10416
Key buffer fill ratio = 21.00 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere
QUERY CACHE
Query cache is enabled
Current query_cache_size = 256 M
Current query_cache_used = 51 M
Current query_cache_limit = 8 M
Current Query cache Memory fill ratio = 20.19 %
Current query_cache_min_res_unit = 4 K
Your query_cache_size seems to be too high.
Perhaps you can use these resources elsewhere
MySQL won't cache query results that are larger than query_cache_limit in size
SORT OPERATIONS
Current sort_buffer_size = 8 M
Current read_rnd_buffer_size = 4 M
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 8.00 M
You have had 53 queries where a join could not use an index properly
join_buffer_size >= 4 M
This is not advised
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
OPEN FILES LIMIT
Current open_files_limit = 17010 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine
TABLE CACHE
Current table_cache value = 8000 tables
You have a total of 385 tables
You have 1155 open tables.
The table_cache value seems to be fine
TEMP TABLES
Current max_heap_table_size = 256 M
Current tmp_table_size = 256 M
Of 89529 temp tables, 10% were created on disk
Created disk tmp tables ratio seems fine
TABLE SCANS
Current read_buffer_size = 8 M
Current table scan ratio = 356 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 87
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'
