Currently, the following buffs are in place:

- Fire giant: +4%hp/5s, 2%mp/5s, +70 magical power, +50 physical power, +15% damage on towers and phoenixes, icon: fire
Previous to the current buffs, since an update in December 2012 the jungle camps provided different bonuses:
- Cooldown: 20% cooldown reduction, white icon with time-circle and arrow)
- Damage: +20% magical and physical power (increasing your damage), icon: red sword
- Mana: +7 Mana/s, icon: blue bottle/jar
- Speed: +20% movement speed, icon: yellow double-arrow

- Gold fury: 300 gold to each teammember, icon: big yellow dot

The normal buffs have a duration of 2 minutes, and the monsters respawn after 4 minutes. Firegiant has a duration of 4 minutes.
Before the December 2012 patch there were two additional buffs: Protection (+50 mag + phys protection) and Health (+10 Health/s). Additionally, the non-buff jungle monsters did not exist yet.
Reference:
To answer your question, one doesn't get to choose spells. Each character has a predetermined list of actions/spells/abilities.
Each character has 5 unique abilities that are broken down into:
- 1 passive ability
- 3 "spells"
- 1 ultimate ability
The reason why I quote "spells" is that not all characters are magic users.
If you have auto level and auto items on (which it is by default) it will automatically level up your spells in the order HiRez (the game developer) has defined. You can override this order by unchecking autoleveling (which means you'll have to manually upgrade each level in game) or if you click on the "gods" menu you can define the auto leveling order.
The 2 abilities you were referring to are known as "actives". Think of an active as an item you can purchase that grants you a special ability. This special ability is on a cooldown timer. You have unlimited uses and once you buy an item you cannot sell it or discard. You only have 2 slots for active items.
You can view all items/armor/weapons/etc currently in game here: https://account.hirezstudios.com/smitegame/items.aspx I recommend sorting it by grid as opposed to list. (blue button, top right)
Please note that the game is still in beta and they do add/modify/remove items frequently between patches so make sure you read the patch notes after each patch.
Some of the items that are considered "actives" are:
- Aegis Amulet
- Blink
- Creeping Curse
- Girdle of Might
- Hand of the gods
- Heavenly Agility
- Meditation
- Purification Beads
- Shielded Recall
- Sprint

What do do as jungler?
The most common approach is to first clear the midcamp on the side of the solo lane together with the mid laner and the solo laner. After that the mid laner goes to his lane and you do two jungle buffs with the support. Depending on your god you either take damage or speed. Then you take the mana buff with the solo laner.
Throughout the game make sure you get to your jungle camps in time, gank mid and solo lane as much as you can to get a experience advantage.
Making a jungle camp in time means that you are there when it spawns. Later in the game this isn't as much of a priority anymore since you spend your time ganking lanes.
Its also your task to call for a Gold Fury or Fire Giant attempt.
Another popular approach is invading. The mid laner takes the midcamp on his own while you and the support try to take the opponents mana buff. They are likely to be here with their jungle, if you can try to steal their mana camp. You don't even have to obtain it since they can't pick it up anymore. This sets back the enemies solo laner a lot since he constantly needs to get back to base for mana.
I am sure there are a lot of other approaches but these are the most common ones.
Item build
Your build is important too, some people start with a 800 gold item and a damage potion which is 400 gold. This is a risk because if you die you lose 400 gold and get behind on the enemies jungler!
Keep in mind that clearing jungle camps is a high early game priority. So you may want to buy some items that help with that, for example 'Hand of the Gods' this can later also be used to kill the Gold Fury or Fire Giant when they are below 25% (Only if its build out).
Team fights
If someone dies in a team fight and the enemy can push because there is nobody who can defend it you have to be a stand in for this lane and defend it until someone gets back to lane.
