Hi...what is the best Wordpress template to use if I plan on placing adsense ads throughout my blog. Also, do i have to cut-n-paste the adsense code after every post?
You can use any template you want to use. There are plugins that place the code in the posts for you so you dont need to copy and paste. You can also edit each part of the template to show ads where you want them i.e. the sidebar, header or footer.

how do plug-ins work...where do i enter the information or tell it what i want it to do...is it in the wordpress control panel, or do i have to log-in somewhere else?
You need to upload them into your plugins folder and activate them within the wordpress control panel. http://codex.wordpress.org/Plugins
I'd recommend use the theme called 'Blix'.Personally I like it very much. You could insert your adsense code into the 'single post' template file,afterwards you could see your ads in each post you've published.
