Don't get stuck in the mindset of needing your ult to gank, even if you hit 6 that restricts you to ganking once every two minutes. For example, a Wukong at lv3 can stealth in with W, E>AA>Q and output about 250 damage in under a second. Some coordination with your laner to bait in the enemy first and you don't necessarily need CC to pull off a good gank.
For clear paths I generally prefer Gromp/Krugs>Buff>Buff>Gank, or half clear then back for junglers with horrible sustain. I only do a full clear on first run with junglers like WW who can both gank right after the full clear and need that lv4 for a much better gank.
Wards counter counter-jungling. Know your matchup to gauge how likely you are to be invaded, always stick a ward when clearing red for the first time, buy a pink and stick it on the outer edges of you own jungle. This is more map awareness than everything. When you're clearing a camp make sure you're looking at other parts of the map, it's not like those camps are going to run away from you.
A successful kill earns your team 450 gold. A successful kill or forced back denies the enemy laner about 100-150 gold (Maybe? I pulled that out of my ass) in terms of missed cs. A jungle camp gives you about 100 gold with little to no risk. Judge accordingly. For large objectives, only start them if your team can handle both the neutral and the enemy at the same time. If, for example, the enemy jungler shows top you know that a fight at dragon would be 4v3 in your favor. Still, always assume available enemies will try to contest. Dragon hurts.
