Some PS2 burning clarifications/help please

[Solar87]

Ok, here's what I plan to do.

1) Pitch in with a few friends and buy this DVD burner.

2) Get some DVD-RAM discs (which? 2.6g? 4.7? double sided or not?)

3) Get a mod-chip(this one ) and install them. (How easy is this installation? My dad is a hellova soldierer and my friend's dad is a surgeon, so we'll pick feasibility/usablity over installation =)

4) Rent games, read in DVD-ROM, burn onto discs with DVD-RAM and place into modded ps2.

Is this ok? Is my hardware alright? Is it really that simple?
Can I use any standard program to simply put the disc into my DVD-ROM and press copy onto my DVD-RAM?

Please give a n00b a little help =)

Thanks much!!
