Having one index with both might help. Adding them to other indexes for your queries would probably be even better.

Very important in all cases.
It should be somewhere between 1 and 100.
In other words, it depends on your data.

As Michael said: More likely to reduce performance than increase it in your case.

It depends.
If you have a lot of selects on certain conditions, then a materialized view based on those conditions can increase performance for those selects.
On the other hand, materialized views,...

SSIS is great for that. For scheduled data transfers between servers, SSIS would be very high on my list of potential tools.

It depends on the amount of data and the connection speed, really.

Your idea is a good one. You might even look into using an indexed view instead to populate the temp table, to improve performance.

There's no performance difference between the two.

In SQL 2008 you could use the DateOffset type, but there really isn't a way to do that in SQL 2000/2005, without building a complex control of your own.
You could...
