Would it help if I add a clustered index to the temp table? The result set should include all the rows from the temp table and so i'm not sure if the time needed to create the index is worth it. Any suggestions?

You could improve your answer by explaining what the items do, and perhaps link to a reference

Clustered index will only improve a merge join. With clustered index no need to sort data from #tmpId. But it's only 9% of your plan. And it will also increase insert time into this table.
