If you are serious about learning Japanese you will need a resource for learning kanji. Japanese for Busy People, and Genki are not kanji resources. The only mainstream alternative to WK, as far as I’m aware, is Remembering the Kanji. It’s a very different system, so I’d recommend researching it a bit to decide whether you think it’s for you. If it’s not, you’ll find WK difficult to replace.
If you go the WK route, you should almost certainly buy lifetime, but you should wait until the holiday sale to do it (when it costs $199 instead of $299). There isn’t much difference between going monthly vs. annual until then: 7 months is $63 at the monthly rate and $52 at the pro-rated annual rate (you’ll get a discount on the lifetime membership according to your remaining annual membership duration).
Since $11 isn’t enough money to break a sweat over, I’d say go with monthly if you have any hesitation at all. Otherwise go annual.
