Need help with a Blueberry Cream Ale

Okay, so I am new to homebrewing and I picked up a kit from a local HB shop.
The kit came with the following:
2.5 lbs golden Light LME
3 lbs Extra Light DME
2 oz Willamette Hops (50 min)
Safale US-05 Dry Yeast

Now my question was with adding Blueberries. I have done some reading and seen that if you want to add blueberries anywhere between 1lb/1gal and 1.25lb/gal. I picked up 6 lbs of frozen blueberries from the grocery today and was wondering when to add the berries, how much to add, and with adding blueberries do I need to reduce the amount of priming sugar (when it comes that time) to make up for the natural sugars in blueberries?

Thanks for all of the help!

Fermenting: Irish Red Ale
Up Next: Blueberry Cream Ale

Wait until your initial fermentation is complete, and then add crushed blueberries to a secondary vessel. I usually rack the beer on top of the fruit into a bucket and allow it to ferment out for another few weeks. Afterwards, rack to a bottling bucket with priming sugar and bottle. There are ALOT of schools of thought when it comes to fruit beers. Do your research and don’t be afraid to experiment. Good luck!
