Is Sliquid Organics good for anal?

It should be fine. However, they do have an anal formula called Sassy Booty.

Yes, I'd go with Sassy Booty. I haven't tried it yet, but since it's made specifically for that, it's probably your best bet. That being said, I've used the gel anally and it's worked just fine.

Yes, but it's not ideal.

look ing for an anls lube...

yes I think so.
