Help me keep my campiagn undercontrol! Options

[GM Lich]

So anyways going to run shadow run again its been a while since I've ran it. The plan at least so far is just to make it an alternative campaign to our regular GURPS: Mass Effect game. One thing we had problems with our previous shadowrun campaign was min maxing. We basically had characters who could do well in whatever field of specialization they were suppose to do. For example the face was rolling 20+ dice. This was in a 300 bp campaign too. It was silly. Basically all the runners could throw a bunch of dice around in combat or in their area of specialization but absolutely sucked when it came to do anything outside their area of specialization. Fast forward a bit that group eventually moved on to other systems and we drifted apart. So now I have a bunch of newbies to shadowrun (and rpgs in general) and one veteran (He played in the min max group.)
So I've been trying to avoid the min maxing nightmare. So I've implemented the following houserules:
core book only SRA, to avoid power creep, all other books are subject to gm's approval depending on what advantages/equipment they are taking
To encourage people to use skills, and be able to be prepare in a number of rather then attribute maxing, they now cost 1 point less per rating to buy in BP
To encourage people not to dump CHA (Besides the face), going to use free contacts = CHA attribute X 2
To prevent over equipment dependency, the total hits limited to skill's rating x2

Anyways just to keep it simple I will run Shadowrun Missions Season 2 (Denver). Right now my worry is the veteran, and people asking to use certain books. Any advice to avoid what was happening in the other group. Any advice running shadowrun missions denver, houserules, and advice would be nice. The two archetypes that seem both really good is that have potential to abuse is the Mage (summoning spirits) and Technomancer (Or should I say dronomancer).
