im amazed by the fact that quite a number of people don't know how to read tabs.. seriously, just look at it for 5 seconds and think, you'll figure it out really. =/

for strumming patterns there's not set rule of any sort. just strum any way you feel sounds good. or play it by ear and you'll do well

you're not a noob, you're just starting out so you've got a lot to learn.
in all seriousness, strumming pattern is kinda like improvising, its kinda hard to teach but you'll pick it up along the way
