Do your homework and check hifishark for current prices. You'll notice it's all over the map, but at least you can extract an average price that will likely sell (the ones with top prices generally don't sell).
The best approach would be to split up the package. Both the Dyna and SME arms are quite collectable and you'll have a better change selling them separately. Selling cartridges is the hardest part, but neither are worth much anyway.
Of course it's none of my business, but why sell? If your aim is to improve the sound, you might consider buying a better cartridge. Both arms are capable of handling much higher quality cartridges and the table is decent enough not to obscure such an upgrade.
