Of course they were not perfect; they were immature, as Matt pointed out. To be perfect is to be complete and mature.
There is a vast difference between being perfect and being sinless. While Jesus walked this earth, He was always sinless, but He was not perfect until He suffered.
For it was fitting that he, for whom and by whom all things exist, in bringing many sons to glory, should make the founder of their salvation perfect through suffering. (Heb 2:10)
"Sinless" is akin to "flawless."
"Perfect" means "complete."
Consider two houses. One is in the process of being built. Excellent carpenters are at work. There is not a single flaw in any of their work. This house is flawless, but is not complete (not perfect). This may be compared to Jesus whose life was flawless, but not complete until He underwent suffering.
The second house is completed. But the carpenters made many boo-boos. This house is perfect, but not flawless.
I see no reason for thinking that Adam and Eve sinned in their hearts prior to eating from the tree. Not to eat from the tree was the only command that God had given them.
They were immature like children, though they had adult bodies. When the serpent tempted Eve, she responded, and thus committed the first sin. When Adam ate also, he committed the second sin.
