Help with Hacking! Options

[nerf]

I'm posting here in anticipation of an upcoming shadowrun campaign. My group has never played 4th Ed, but most of us have experience with a house-ruled 3rd Ed. In 3rd we always ignored or NPC'd the Matrix aspect of the game, for reasons everyone here understands, I'm sure.

Since we'll be playing SR4 this time around, I'm really looking forward to including that aspect of the universe. Unfortunately, none of us really understand the Matrix rules very well. As we are discussing our party builds, I had the idea for all of us to dedicate 40 BP or so to hacking. I think this could be much more fun than one person dedicating 400 BP to being a technomancer or dedicated hacker. The other benefit, is that we can all learn the rules together.

Playing around with a character builder, it seems like it's reasonable to buy a nice commlink with a hot sim module and a few rating 4 programs for less than 10 BP. Add a rating 4 skill or 2 for 16 BP each and we're all throwing 8 dice plus Logic for our Matrix tests.

I figured we would break up our specializations into something like this:
Matrix Perception / Data Search Guy
Stealth Cracker
Matrix Warrior

Any feedback would be appreciated. What skills/software are needed for each role? Is this idea stupid or impossible for some reason that this Matrix noob doesn't understand? Thank you Dumpshock!
