I do this all the time. Add the full pack of yeast, having more active yeast is not a bad thing.
If you split up a 5 gal recipe and use 1/2 the malt watch your hop rate. Make sure its 1/2 too. Or do as follows;
3.5lbs / 6lbs = 58% : Use 58% of the hops : (Example: 1 oz of cascade x 58% = .58 oz)
3.5lbs / 5lbs = 70% : Use 70% of the hops: ( Example .50 oz of cascade x 70% = .35 oz)
The 5-6 lb malt suggestion can make a difference if its lightly hopped. For example, if you make beers once with 5lbs and 2nd time with 6lbs and do a side by side comparision. You will see a big difference in taste if you hopped & boiled at the same rate. The 6lbs will be less bitter if not noticably sweeter.
I learned this after being told you can substitute DME & LME pound for pound. Not so true without effecting the flavor.
Since you are using prehopped it shouldn't be too big of a deal. I imagine your hop additions are late (after 15 min) so they will mostly affect flavor and arroma, not bitterness.
