Replying to Questions about living at Mt.Hood

So, I am really considering ski bumming at Mt.Hood this summer by myself or with one or two buddies. We all have a couple questions though and would really like some advice from people who have done this before. Anyways:

Do we need a car?
Is it possible to get to everywhere we need to go within walking distance/biking distance?
Best affordable places to live/camp?
If we camp is there anywhere to get Wifi for free?
If we camp should we bring any electronics?
What's rent like for apartments?
How often will I be able to ski if I work at Timberline Lodge?
Whats working at Timberline like chill/not chill?
How many days a week will we probably work if were just doing basic shit jobs?
Best way to get to Mt.Hood from the airport without a car?
What should we bring or not bring?
How much money should be bring for supplies and food?
Whats the wage per hour at Timberline?
Should we bring more warm weather clothes or cold weather clothes?
Is there any place to shower if we decide to camp out?
Lastly is this even possible for a bunch of 18 year old kids to do?
