What extra work? We used cloth in conjunction with EC (elimination communication) from the start and I couldn't imagine using disposables--having to run to the store to pick up extra packs of diapers, running out extra loads of trash, finding places to store the diapers and trash in my tiny apartment etc. :D With cloth I just tossed the diapers in the wash when I got a bucket full, and hung them to dry--10-20 minutes spent on laundry compared to a 1-2 hour shopping trip with a baby in tow ;-), but really it depends on what you're used to, I guess.
Things you will want to look into are:
Finding a diapering system that works for you. (I'm guessing that you are getting flat or prefolds, but there are tons of diapering systems out there.) Look into AIOs, AI2s, Fitted diapers with covers, pocket diapers, contour diapers, covers with lay in soakers etc.
I personally like this style fitted:

with a wool cover over it. But there are lots of different styles and brands.
Many people find that they have to change more often when switching to cloth--depending on your son's metabolism and how often you changed him in disposables you may find this true as well.
Getting a laundry detergent that works with your water, so you don't have residue buildup and the diapers actually are getting clean. I run the diapers the same way I do all my other laundry, but some people find they have to do a pre-wash or extra rinse cycle.
here's a helpful chart on laundry detergent:

Also, depending on your location, a cloth diapering service might be an option for you. You will only have prefold diapers with this, but on the up side, you don't have the extra laundry to do ;-)
Other than that, I can't think of anything challenging about cloth diapering. But on an EC front--offer your son the chance to sit on the potty whenever you change him--if you're lucky he'll start to pee for you and save a diaper or two :D Also if your son is regular and has his BM at a certain time every day, sit him on the potty and read a (short) book--it'll expose him to the potty, maybe keep his bottom clean and dry longer and hopefully save you some diaper laundry and diaper changing struggles ;-)
HTH,
