Transitioning to a Hacker Role..., My sammy gets depth! Options

[Octopiii]

I've been thinking about adding hacking/rigging capabilities to my Street Samurai, both to fill out a need and to give him something to do other than killing people. Now, I have never played a Matrix character before, and while I think I have a good grasp of the matrix rules, there's always something to be said about actual application of said rules. For the immediate future, all I'm likely to do is buy a Fly-Spy to give the team some extra scouting ability. For long term planning, I am thinking about getting a(n) Agent(s) to handle all my common use programs and just focusing on illegal applications, allowing me to ignore the Data Search and Computer skills and having him focus on Hacking and (maaaybe) Cybercombat. I will likely remain in AR for my hacking/rigging purposes, unless I am planning to do a slow probe of a target.

Here's my character, currently:

Now, I will have ~20 karma and if we actually succeed on our run ~40k once we get back from B.F.E. to the sprawl to play with. What skills should I get? I should probably pimp my commlink out, right? (I think it is currently at 4 in every stat, and I have all common use programs at 4). Is a rating 6 agent worth the cost to upgrade everything, or should I be happy with rating 3/4? I think I pretty much have spy-type rigging covered with my current skills, except for combat which I will honestly be more effective doing in person and vehicle driving skills which is a niche that is currently filled anyway.
