Go for it. Thor's series has been quite good ever since it relaunched in '08. Keiron Gillen is writing it now and he's doing a good job. The solicitations for future issues are a bit of a mess because of Marvel pushing the start of Fraction's run back by like four or five issues, but I'm pretty sure Thor and Clor have their showdown in the next issue and then Thor has to go to Hel to deal with the Disir, a group of ancient spirits who were basically Thor's grandfather Bor's attempt at creating Valkyries before Odin did. They apparently eat dead gods' spirits, so, y'know, fun.

The two characters are totally unrelated. Beta Ray Bill's a trusted friend who was granted similar powers to Thor by Odin. Clor/Ragnarok is a cheap knock-off that Reed Richards, Tony Stark, and a Skrull impersonating Hank Pym stuffed with machinery to imitate Thor's powers.
