I've attempted the alter table cache option, which occurs almost instantaneously, but it does not see to make an impact on how the query is run..is that the only way to install a table into memory? thanks.

it will not affect performance dramatically. look at other tuning techniques to improve performance like indexes.
using explain plan command ,you can get info about how oracle access tables when you issue query.basically, you have to optimize query to get good performance and in better response time.

And if you're using Oracle 8 or above (or Oracle 7 with the Cost based optimiser), don't forget to anaylze your tables once they've got a reasonably normal usage amount of data in them, or Oracle will use probably the worst access path possible :)
