Question : Optimizing Oracle 10g, recently upgraded from 8i

Hello,
We just currently upgraded from Oracle 8i to Oracle 10g and have notice some performance issues.  Most of our queries are dragging.  The install was done by an outside provider and they didn't utilize 10g's upgrade assistant.  The box has 2 gigs of memory and the database is roughly 8 gigs.
Any suggestions would be greatly appreciated.  And if you any other resources, just ask :)

Here is our initXXXX.ora file.
db_files = 80                                                    

control_files = ("/u02/oradata/XXXXX/xxxxx_ctl01.ctl",
                 "/u02/oradata/XXXXX/xxxxx_ctl02.ctl",
                 "/u03/oradata/XXXXX/xxxxx_ctl03.ctl")

open_cursors = 500


_use_ism = false
db_block_buffers = 33280  
db_block_size = 8192    


shared_pool_size = 200000000
java_pool_size = 160000000
large_pool_size = 160000000
pga_aggregate_target = 25165824
session_max_open_files = 20

log_checkpoint_interval = 10000
log_checkpoint_timeout = 1800

processes = 275  

log_buffer = 2097152  
rollback_segments = ( RB01, RB02, RB03, RB04, RB05 )

background_dump_dest = /u01/app/oracle/product/10.2.0/admin/XXXXX/bdump
core_dump_dest = /u01/app/oracle/product/10.2.0/admin/XXXXX/cdump
user_dump_dest = /u01/app/oracle/product/10.2.0/admin/XXXXX/udump

remote_login_passwordfile = exclusive

os_authent_prefix = ""

compatible = "9.2.0"
sort_area_size = 2097152  
sort_area_retained_size = 65536
