Fixing problems importing an android project from Eclipse to Android Studio

yesterday I decided to switch from eclipse to android studio and I had a huge list of problems in achieving this goal!
The android project in eclipse uses three project library and some external libraries: one of them is a library that I created as a support library for all my apps, another one is the NineOldAndroid library, then I have the FacebookSDK library and appcompat and some jar libraries for example for using json and xml.
I have open the Android Studio and I imported as an eclipse project and woah at first it seemed that everything went good but from this point a series of problems start to bother me!
First of all I had a lot of import problems and I solved all (I hope!) and after a lot of google-ing I found some configuration for solving others, the only persisting is the one bounded to the FacebookSDK: android studio can’t find a lot of resources that belong to appcompat.
Someone can explain me this?
The gradle file of the FacebookSDK is:

apply plugin: 'com.android.library'
android {
    compileSdkVersion 19
    buildToolsVersion "22.0.1"
    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 21
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}
dependencies {
    compile 'com.android.support:appcompat-v7:+'
}

I’m pretty sure that the problem is the fb sdk because I tried removing it completely from the project and my app started without any problems, but I need this sdk! How can I fixed it?

A little piece of the error list here:
