For your first question: select all the notes by positioning the cursor at the start of the line a pressing Shift+End. Then hold down Ctrl+Shift and press the down arrow (on your keyboard) five times. Finally, Change the clef by selecting it, press Alt+Enter and choosing treble clef.
For your second question: Press the scripted i on the toolbar. This gives you room for 1 line for the title, 1 line for the author, and 2 lines for the copyright. At present, that's the best you can do. Post-precession can aid in that area, however. By placing the WMF's from the print preview's copy button into your word processor, you can add snazzy text effects and even adjust placement of some things.
For your third question: Select the notes is question, and hit Alt+Enter. In the notes tab, you should see slur direction. Choose Upward.
