I would make the promoter constructs contain the 5' UTR just to be safe.
You may to make a few different constructs....constructs with the UTRs,
constructs with out UTRs, constructs with leader peptides, deletion
constructs, etc........Just to be safe.  I have read many plant promoter
papers and most papers that I have read have the 5'UTR in the promoter
construct.  This may be different in other organisms.

I have never used GFP-GUS fusions before, but check out this paper
Quaedvlieg N. et al.  Fusions between green fluorescent protein and
B-glucuronidase as sensitive and vital bifunctional reporters in plants.
Plant Molecular Biology  37:715-727. 1998.
