about set up the wireless, the card should be working without your intervention so no driver required or already installed(if not connect the ethernet cable and search for sis163 in synaptic and add it to the install)
now, open pclinux control center/network & internet/setup a new network interface
there you follow the steps to add the wireless interface
after that from the detected networks you can choose and give the password to connect to your wireless network
near the clock on the taskbar there should be a icon to configure network adapters or search for networks, the previous steps i mentioned are sometimes more simple to follow and doesn't depend on the icon that could be removed from the taskbar
about the battery monitor, in the desktop just where you see the wallpaper right click/unlock widgets and then right click/add widget
a menu will offer you many objects, write battery in the small search window, onshe found drag/drop to desktop or to the taskbar near the clock, where you see it will be more useful to you
