So I did a practice game with him and this is what I built:

I'm not sure how right this is. Could I get some help please?

/another defensive item
I shit you not Trinity Force is actually a really strong item on Cho
This is meh. You want 40% cdr as Cho'gath and you either build as an AP carry (mostly) or as a tank.
AP carry build would look like

Tank build would look like

Well, I think you need armor I would probably swap GA for FH. I'm not fan of GA though
I switch every game, but I try to go like this:

It depends on the team compositions and the situation in-game.
Typically, you want to aim for a mixture of AP, CDR, and durability. However, the specific items will frequently change.
You can build it ap if you're ahead and you have no other ap in team(if you already got a tank in jungle and an ad on mid(Talon/Yasuo):
for example. That's a very offensive ap build. But it's kinda hard to survive if you don't have stacks so I recomend to replace one of the item with a defensive item like
or
.
If you're not fed or you already got an ap carry in your team you can go tank. You'll still be useful because you got a knock-up, a silence and your ult does true damage.
Anyway, you should begin with
and then go with more defensive items like:
(for extra movement speed, it will be very useful)
(for more mana, CD and a nice passive)
(if the enemy adc is fed then Randuin is a must)
(you can get this item as second item, after Rod of Ages, it will help you to farm faster)
And if the enemy got a fed ap, then build
or
.You can take this item too
. It will help your teammates.
You can take those items too, they are great
