Making some changes in a pattern

I want to make this http://www.maizehutton.com/easyponcho.html

I don’t want to use just garter stitch. I understand how to change that part. I’m not sure what stitch I’m going to use yet, but I was thinking something with eyelets or a lacy type.

I also don’t want to use bulky yarn. I want it a little lighter. I know how to adjust the number of stitches but would you suggest using 2 of a light weight or may just light or regular worsted?

Also how do I determine how many skiens to buy?

Thanks for all the help, I know it’s a lot of questions…
