Is there no way to call the stored procedure and pass it a table?
There is, if you're using SQL Server 2008 or higher: table-valued parameters (TVPs).
I've already blogged about how to use TVPs in SSIS. Essentially, you have to use ADO.NET inside a Script Component. While this isn't the prettiest solution, it gets the job done relatively cleanly with all the code in one spot.
I know raising the transaction isolation level and adding a transaction can seem counter-intuitive, but sometimes, you have to make things queue up and wait their turn. Doing those two things worked for me in my simple test rig. Try it and let us know how you get on.
EDIT: Test rig
OK, nice simple test rig using tempdb. It's a bit rough and ready but provided an easy repro and provable fix for me. You should enable SQLCMD mode in SSMS before you run. I basically pit the proc against itself in multiple sessions using either ostress or GO 100. Run the initial version of the proc, monitor for deadlocks; I get many. Then, reset the rig, run in the revised version of the proc and try again.

The question is unanswerable as asked since stored procedures do not produce result sets. Only (certain) statements produce result sets. Executing procedures may produce none, one or more results sets depending on the statements contained and the branches executed.
For statements the row count will be tracked in
sys.dm_exec_query_stats.Result sets have no size (in bytes or KB), size is an attribute pertinent only to encoding and representation. A sensible question would be to ask how many bytes are transferred between the client and the server, and this can be tracked by transport performance counters.
