A few questions: scribble, raise to speak and raise to wake?

watchOS & Apple Watch Apps

Hi everyone! I recently got an Apple Watch. For the most part, I've been enjoying it and have been able to figure things out, but I had a few questions I was hoping you guys could help me with.
- I see that the only way to enter a wifi password is using scribble. Any tips for making this work? I wasn't able to input the username and password for the network.
- I turned off the "raise to wake" setting because I move my hands a lot (touching things, walking with my guide dog), but then the screen wouldn't wake up easily, even if I tapped it and left my finger there. What settings have worked for you as far as waking up the screen? I want the watch to be responsive without killing the battery.
- Finally, has anyone gotten raise to speak with Siri to work? It seems like a cool idea in principal, but I couldn't get it to activate no matter how close to my face the watch was.

Thanks so much for any help you can offer.
