Go to the parser, either linked above or in the dropdown, and search through the list for what you are looking for.
Clicking on the release you want will bring up and dialogue box, where you can copy the XDCC line needed to download.
Join IRC with a desktop client to be able to download from the XDCC, something like mIRC or HexChat will work.
Paste the XDCC line you copied from the parser into chat, and the XDCC bot will send you the file. Repeat for each file you want.
