Of course don't rebuild needlessly; check the stats and only rebuild those indexes that require it.
Also, with a reasonably well-tuned tempdb, you should strongly consider using the:
SORT_IN_TEMPDB = ON
option. ...

You want to use a T-SQL script to do the backup and restore, not go thru the GUI. That will speed up and simplify future repeats of the same...

Yes, my initial concern wasn't with performance per se but with readability/understandability.
Since PARSENAME is available, fully tested and documented already, I would use it in preference to hand-coded SUBSTRING,...

After a bit of testing, I can confirm that PARSENAME does win much more often over use of CHARINDEX with SUBSTRING's than other way around.

SQL Server has frankly always had some internal issues with parallelizing queries. Parallelization is great for (re)building indexes, but for queries it's always had its quirks.
Unless you are absolutely...

my simple goal is to create a two part job that will reindex only the items that need it ...
select 'ALTER INDEX ALL ON dbo.' ... 'FILLFACTOR = 80'...
