Yup, the two spells stack (due to one being an<em>armor </em>bonus, and the other being a<em>shield </em>bonus). Shield is considered "better" because it absorbs magic missiles, which is why it has a lower duration.<br/><br/>Beyond the feats at level 1 and 3, you will have another feat if you are human (see the human racial traits)<br/><br/>Also, dont forget that each level in your favored class you get either +1 hp or +1 skill point
