Welcome! Not to reiterate what has been said before, but these two are serious passes (Icidid by far the harder of the two), but route finding will be an issue if you haven’t done them before, especially if you encounter rain or mist.
You can obtain much more information about many of the Drakensberg passes on Vertical-endevour.com (VE) as well as download tracks for these and other passes. You can also find out on VE if you can tag along, hikers post their planned trips on a thread called “Upcoming hikes”, which, if you are new to the Drakensberg is a very good idea as you will get to know the area with experienced hikers.
My suggestion for a first time hike (please note this is just my opinion, you are free to do as you like) is to go from camp to the lower berg (2000m to 2300m generally) on Day1, then on Day 2 you have the whole day to get to the top of the escarpment and sleep on top, and Day 3 go back down to the carpark.
As a very rough guideline, starting from the North, The Mnwenin area has long walk-ins and pretty rough terrain, below that Cahedral peak is the shortest way to get to the top (my preferred place to bring new hikers to the Drakensberg) with generally good trails. Then Moncs Cowl area is also really pretty with decent paths on the lower berg, but relatively few passes to get you to the top. Immediately South of here you will find my favourite area, Injasuthi, but to get to camp you need either really good offroad driving skills or a vehicle with good clearance. Generally good parths but overgrown in many places, but spectacular mountain passes, most without a decent trail so you are in for lots of bundu bashing and rock hopping. Gaints is a bit far from Gauteng (don’t know where you are from) but also great paths (difficult to get lost here) and relatively easy passes.
There you go, the rest is up to you
