Power supply - battery/esp and others

Hello.
I've just discovered esp8266 (I have some 01 versions). I guess like many - trying to networking with arduino.
But as far as I can see I don't need arduino at all .
Just starting with ESP modules. Even programming is not so trivial as in arduino case if you are not prepared (I've needed to "hack" my usb2serial converter adding button for programming), but there are many possibilities.
And here are questions. I want to make some devices, part of them will use laser diode. I want them wireless, so I need batteries.
- may I use typical Li-Po battreies (3.7v) with esp8266-01 module (3.3v)? Is it too much for them or not? How to handle it?
- may I connect laser diode (3/3.3v, 5mW) directly to esp GPIO pin? I don't know the currencies.
- if both answers are "yes" - what will be the signal level on GPIO in this case? 3.3 or 3.7 (more or less)?
