Hi Happy,
I have only used HT with my baby and he likes it. I haven't used Earthbest before.
In response to your 2nd question, let me share with you my feeding schedule for my 7 month-old. Milk when he wakes at 8am, rice cereal+milk at 11am, oatmeal at 2pm+milk, porridge at 5pm, and milk at 8pm. You can switch the solids around the different time slots depending on your convenience - it doesn't make a difference to baby. He is eating solids well but I make sure he drinks a minimum of 20oz of milk/day.
