I have used the Beechnut feeding guide for my last 2 kids to get an idea of portions and how much and what to feed them. Don't feel that you have to use Beechnut foods just because the guide comes from them... use Beechnut, Gerber or whatever brand you prefer, use the guide for the other information.
Info below copied from their "about 6 months" category... they also have an "about 8 months" category.
Variety at Feeding Time
Every baby is different. Yours will let you know how much she needs to eat and what she likes or doesn’t. She'll also eat different amounts on different days. This helpful guideline will help you plan her meals. Print it out and put it on your refrigerator for reference.

Breast milk or formula – 24 to 32 ounces in five to six feedings, fed with meals or in between
