I like Adobe Premeire for my movies that i edit. Adobe is great for me. You can do alot of stuff with it and once you get everything down it's not that hard to remember anything.
You need a firewire card and a free slot to stick it in, in your computer. the attached picture is a firewire card.
you also need a farely fast computer. You should have, at the bare minumium, 256MB of RAM. you can find how much your computer has at

When you talk about "menus on the screens" do you mean like what a DVD has? do you want to make DVDs? if you want to make dvds, you need a DVD-R(W). These are pretty expensive if you get a good one. the actual DVD's that the movies go on are really expesive compared to normal CD's also. A DVD-/+RW that i randomly clicked on the best buy website is $129.99:

If you want to make the menus and you have the DVD-(+)R(W) rom, you will need DVD editing softwere. Adobe will just let you edit the movie but it won't let you put it to DVD (at least the version of adobe premiere i have). i don't know of any dvd editing softwere out there...
