Erase my iphone through Find My iPhone?

I need to restore my iPhone 5 since I was locked out due to my forgetting of my pass code, and the only way to do this is to erase through Find My iPhone. However, it says that I will not be able to track my phone after doing so. If I erase my phone and then reinstall Find My iPhone on it, will I be able to track it anyways? Also, after erasing it, if I sync it to my computer (which I believe I've done before) will I be able to get some apps, photos, music, etc. Back?

Yes you can erase and reinstall findmyiphone.
