As for your questions:
1. Sometimes you can get extra discounts when entering promotion codes. I am not aware of any valid promotion codes at this time, and you don't need one for the free upgrade.
2. If you want to go up the Titlis, you can use your Swiss Saver Pass to travel to Engelberg for free. In Engelberg, you walk to the cable car station where you purchase your Titlis ticket. You will get a 50% discount on that ticket if you show your Swiss Saver Pass. Depending on where you're from, you may or may not be able to purchase a Titlis ticket online, along with the Swiss Saver Pass. I don't think it's possible for the countries listed in my post.
3. You will receive a regular 1st class pass but pay less for it than you normally would. All you have to do is have it validated at a Swiss rail station before your first trip. After that, you can just board all trains for 8 days.
Enjoy your trips in the Swiss Alps!
