If that is the case, are there any advantages to using a table variable over a temp table? ...
Is there actually any advantage over using a session scoped temp table?
AFAIK,...

"A Table Variable can have primary keys and indexes defined." I don't see the word "you" in there. Can indexes be defined on a table variable? Well, they can exist,...

Computed columns are generally very efficient.
Also, they keep the column name the same for everyone -- CTEs get re-coded and so the column names can vary greatly from one piece...

if I included those computed columns and accessed the table via a SELECT * query elsewhere, would it also return those columns?
Yes. In that case, SQL would consider that...

You could use a DDL CREATE_TABLE trigger to:
1) rollback the CREATE TABLE if the schema is not dbo (this should greatly help in forcing others to explicitly change their code...

Yes, MERGE would be applicable to that scenario.

Unfortunately, I can't add anymore columns to the existing table without causing it to bloat up more.
Keep in mind that computed columns are NOT physically stored in the table,...

Since there's only three dimensions being tested, I wonder if it's easier to just add computed columns to the base table and do all the calcs inline in one query,...

A sysadmin can't be denied anything in SQL Server, so something else is going on here.
Is this a SQL login or a Windows login?
If W, is it a group or...

Is there a sql statement that could turn it into this?
Yes, look at PIVOT as well.

When the table is truncated the table is reseeded with values back to 1 again.
Technically, the table is set back so that the next row inserted gets the initial...

You really should use the sys.* views to generate the code, rather than using the INFORMATION_SCHEMA views, because, according to Books Online:

written an SP that uses a table that doesn't exist
I think your best chance is to try the following DMVs:
sys.dm_sql_referenced_entities
sys.dm_sql_referencing_entities
Other than that, I don't of anything else within SQL...
