Man, I feel dumb posting this!

Alright so basically I got my Alero 4 months ago as my first car for my 16th birthday. After looking for about 3 months on somewhere to get advice on my Alero I was extremely happy to stumble upon aleromod.com!
Having this be my first car, I have no idea where to start with the audio, I need new deck speakers because mine are blown and I'd like to replace the head unit along with the front door speakers.
I have a 2004 Alero 2dr.
So what I'm wondering is what everyone suggests that I get put into my car, I'm looking for some good deck speakers that will thump and a nice head unit compatable with an iPod Classic. I'm not looking to spend more than 200 right now so Apline Type R and all that good stuff is out of the question.
I'm just looking for something that will last me a decent amount of time and will sound good!

Then after I figure out what I want, I need to know how to install it or if I'm just better off going to a audio shop.
Last time I posted some guy said to use the search button and thanks whoever said that but everything I come across, I don't understand.
I think I have a good idea on how to install my deck speakers but what parts/wiring do I need to install new deck speakers? Do I need a wiring harness?
Then how do I install a head unit into an Alero? Again what parts/equipment and stuff will I need for this?
Really my big question is on the Head Unit and how to install it when I get my new one!

If you can't help me with the installing part don't post a comment about it! Please no stupid comments because I already feel stupid posting this! But, I'd love to hear what everyone want's me to get installed for my speakers!
Thanks for anyone who helps!
