tracy61 on "Windows Live Space Newcomer Requesting HELP!"

Having recently been "redirected" to WP from Windows Live Space, I'm feeling a bit overwhelmed as a "newcomer".
Using Live Spaces allotted user's to customize their spaces fairly simplistically. Though there seems to be a large array of Templates out there for users in WP, I'm finding the "customization" options to be quite cumbersome, let alone the whole "learning curve" routine. Needless to say, I have a few questions right off:
1. Will I really have to do the CSS upgrade to accomplish any type of "customization" to templates used/downloaded?
2. How may users best learn CSS if they decide to stay with WP?
3. Can you style WP templates via HTML or just CSS?
and for starters...just one last question....
4. Can you have multiple blog type pages? Example: I would really like to add an additional "page" for which I share recipes; allowing search options etc.
Thank you in advance for any and all assistance you may offer to me (and other) newcomers. :o)
