How Can I Create A Web Site Which People Must Log On To In Order To View Its Content?

I run a small school and was hoping to create a web page which the pareents of my students could log on to to view up coming events, due dates, school news, etc. Eventually I would also like to set up a system with which it would be possible for them to pay their monthly tuition online. Any tips for this little venture?

Please Describe The Easiest Way To Create A Podcast Of My Minister’s Sermon And Post Online For Members.?

I would like to:
Create a podcast of minister’s sermon.
Preferably, minister could have a lapel microphone.
I am willing to spend ~$500-1000 for ipod, microphone, other equipment.
Speaker/Minister is not currently hooked into sound system or using a microphone.
Sound system and accessories should be easy to setup and store once a week.
Would be really cool if we had another microphone that could roam in a small room when people have questions to get those recorded as part of podcast.
Once podcast is created need an easy way to post those podcasts so that members can go download. If I could have a static url members access at the church web site that would link to a library of sermons (sorted by date and titles) that would be ideal.
I am moderately tech savvy. Examples, I have 3 ipods and use iTunes, I can setup my own router, I just setup my Slingbox last week, I generally like tinkering with technology and software products.
Thanks for your help!
