Answer 1

It is is difficult to give you a very meaningful answer. Have you looked at the disk I/O costs ? Where are you keeping the database files - perhaps it is the I/O that is stalling ? There are so many variables here that can affect the performance. Perhaps it is the time taken by your UI or whather to display the data, perhaps it is the time taken by the Network ?

Perhaps the easiest way - where you will see the most gains will be to partition the table - if you are on the Enterprise Edition of SQL Server 2005.

Again without having access to actual query plans, perfmon stats it is mighty hard to tell you exactly what is the problem. Your question simply doesn't give us enough to go on - and everything is just a guess.
