First time purchase help... Are bow "packages" worth the money?

Just got home from the shop with my new bow... of course I can't shoot it because the glue on the arrows has to dry! How disappointing... I guess that gives me an extra day to decide on a target.

Mission Riot 28" 57lbs
Impact Fiber Tech sight
Rip Cord fall away rest
4.5in Limbsaver stabilizer
Alpine Solt Loc 5 arrow quiver

Beman ICS Hunter arrows
Scott Shark release

Now that I'm playing with it I realize the string isn't quite touching the corner of my mouth when I draw back. My nose is touching but by my mouth its just a hair above the corner of my mouth. As long as I do that every time that shouldn't matter right? Or should I tilt my face a bit up so that its in the exact corner and then adjust the sight? It's not something I really noticed while test firing.
