EA StaffHey @nppdwyer,
welcome to the dark side of the forums.
If you purchased the Ultimate Edition, you should have instant access to the DL-44 blaster, the Ion Grenade and the Ion Torpedo. It does also comes with the Season Pass that includes all four expansion packs. The other weapons are unlocked by leveling up and purchasing them with credits.
The Ultimate Upgrade Pack you mentioned would be a shortcut to unlocking 11 weapons and 24 upgraded Star Cards without having to level up first.
If you have any more questions, just shoot.
