Looks like a good start.
If you want to net five gallons, might add .5 to 1lb DME, looks like gravity might be a bit low with 4lbs.
Also, IBU's of 69 is off the chart for the style, but if you want more of an IPA than a Pale Ale your OK.
You don't mention when you intend to add your hop additions. If you want to get IBU's "within style", here's one recommendation:
.5 oz Cascade (5.5%AA) 60 minutes
1 oz Centennial(10%AA) 30 minutes
1 oz Saaz (4%AA) 5 minutes
That would put you ~39 IBU's, near the upper-mid range for the style.
BTW, I use that Safale US-05 yeast on all kinds of beers, and love it. I've brewed 15-gal batches of various stouts, IPA's, pale ales, etc, and split the batches in three so I could compare US-05 to more expensive, "authentic", and time-using liquid yeasts. Couldn't tell much (if any) difference between them. I always keep a packet or two on hand, just in case anything happens to a liquid yeast starter.
