Follow through the 3.1-4.1 tutorial in my sig below. This will install both bootmii and priiloader, which are both great to have. Since your wii is old enough to have been on 2.2 you should be able to install bootmii as boot2 - make a NAND backup and you'll be able to recover from just about any brick.
Right now priiloader isn't working for you because it requires 3.2/4.0/4.1/4.2 to function. Using the guide below can take you to firmware 4.1, if you want, which will also give you the ability to load channels through your sd card.
