So, bottom line is that isn't a CZ iCourier. Looks more like a general use ship. Certainly not the kind of build that makes me facepalm, but not a combat bred ship either, and CZs demand combat bred until you're talking ships to withstand heavy fire.
That thing needs PE thrusters immediately. Just do it. Then learn to shed mass to get the most out your speed.
I would also move away from thermal-heavy loadouts until you can comfortably farm a CZ to the point that ammo is your problem.
So I might recommend something like this:

Immediately I'm doing things like losing the MGC armour in favour of two C1 HRPs. Instead of 8T for less than 140 HP, the ship gains 2T for 220HP.
The bursts are gone and replaced with two MCs. These things will be much more potent for you. Easier distributor management by miles for higher damage output. You can roll a low-grade Efficient mod on it and there are NO offsets to this mod, so there's nothing to be lost by putting it on. You then have the option of applying effects after a few rolls; I can recommend one MC gets incendiary (PvE only) and the other gets corrosive.
I would also roll the efficient mod on the PA and again if you roll enough to hit G3 and burn rep for effects, dispersal field. But if you're not into working the engineers enough to burn rep effects are optional - I would however replace the PA with a traditional pulse lazor or similar; in PvE, PAs aren't actually great shield breakers, and so two multicannons without effect will burn through ammo quickly to break shields, where one of the MCs with incendiary will do most of the shieldbreaking for you.
I can also recommend, IF you have the money, downgrading to a 2D FSD and halving the size of the fuel tank. It makes a serious difference to your speed. The reason you need money for that is you have to transport the ship everywhere, which is gonna be about 60k to 90k for a respectably sized trip in the bubble.
Finally note the change to utilities, which are much more robust for a CZ - two D rated boosters and two chaff launchers. As you aren't likely to overheat yourself in PvE unless you fire off an SCB, which I removed because it's not much use to an iCourier, I missed heat sinks and included an AFMU. This would allow you to heal moderate heat damage to your modules, probably after battle as your ship will unlikely be able to power it at the same time as every other module. And when you get into big boy mode and can reliably survive each encounter with shields up, get a C2 bi-weave and engineer for resistances.
Now that is what I might recommend for a CZ but by no means is what you have to use. Feel free to draw inspiration from what I've put forward and make it your own (Y) On the other hand I do know the iCourier, and if you can fund the ship I put forward, you'll see that it lacks the utility for anything but fighting - but for that fighting has more bulk in both shields and hull, has double chaff, and yet is over 100 m/s faster unboosted, with about 140 m/s extra boost speed. That's a lot.
If you want a more MR ship feel free to adapt something with more utility. If funding is an issue...I'm sure I can help you in game.
