Spicing for a pumpkin ale

Greetings all.  I brewed a pumpkin ale up a week and a half ago.  I’m aiming to make something in the vicinity of ST Pumking.  Here is what I brewed:

2.25 lb                Pumpkin (Mash 60.0 mins)

0.50 tsp              Irish Moss (Boil 15.0 mins)                       
0.50 lb                Pumpkin (Boil 15.0 mins)                           
0.60 oz                Sterling [7.20 %] - Boil 15.0 min           
1.0 pkg                SafAle English Ale (DCL/Fermentis #S-04)                     
9.2 oz                  Brown Sugar, Light (8.0 SRM)

I am racking it to secondary onto two vanilla beans for a few days.  I plan to add my spices to my priming solution at bottling.  Where I am a bit stuck is the spices and the quantity.  I’m kind of flying blind and don’t want to screw it up.  So, I would appreciate any insights from the experts.  What I originally had in the recipe was:
1/8 tsp  Ground Ginger     
1/4 tsp  Ground Cinnamon
1/8 tsp  Nutmeg
1/8 tsp  Clove

How does this look?  As I said, I am going with the “spice tea” method, so I think more flavor will carry over. Plus, it will be only 3 gallons in the secondary.  Alternatively, I could just use “pumpkin pie spice” but have no idea as to the amount.  Thanks!

I think the amount of spices you have listed sounds fine. I would definitely recommend adding a small amount and tasting to get the flavor where you want it. The one spice that comes through very easily is clove so keep that in the lower side of qty.
