UPDATE
It is possible to use Photoshop with Camera Raw instead of Lightroom for processing. For me, Lightroom is much more streamlined, intuitive and faster for basic processing - I much prefer it. But Photoshop is better for retouching and making more dramatic and artistic changes.
In the video I recommend exporting to Photoshop before exporting to jpeg for the web. First of all, you can do this much more quickly than I do in the video using the shortcut Command-E, which will open the image in Photoshop directly without needing to save a file. However if you don't need to retouch your image, you can resize and convert to jpeg/tiff etc directly from Lightroom.
I don't talk about colour space as much as I should in the video. I highly recommend learning about it, if you haven't already, and I've put a link to a good tutorial by StyleMyPic below (check out his other videos too, they're re really good). Lightroom natively uses a 16 bit ProPhoto colour space. If you do need to export to PSD or tiff for further editing, keep it in ProPhoto (rather than Adobe RGB as I say in the video) right up until the time you need create a copy for the web. In which case then you should convert it to an sRGB jpeg, or Adobe RGB tiff if you're sending it to a print lab.
