I'd skip any pale liquid extract. Unless you find 100% wheat extract, they usually are a blend. If you shop around, you might be able to find a brand that is a mix of wheat and pils.
Also, I really like using 3068 lower in the 63-65 range. The hefewiezen rule of thumb is that your pitching temp and your fermentation temp should add up to 30 (in celsius). I find cooler temps make for a much more balanced beer. That is unless you want a bananna bomb.
