So, plainly enough, you did not actually read the option to keep the base intact, but dedicate it to _all_ humanity and its allies, and not only Cerberus ?
Indeed have to check that. The wikia guide is also silent on that option (only has destroy it(Paragon) or keep it for Cerberus(Renegade)). What do you mean precisely?
.......
Uhm, there is a big space station full of the scum of the universe right next to the relay and it should be pretty obvious pretty fast when suddenly a bunch of human ships uses it instead of Collectors. Sounds like information worth selling to everyone or try investigating further yourself to me. Good luck to Cerberus if any of the merc groups, Batarians or some of the Council agents get a whiff of that. They just have to put a bunch of ships there and board anything suspicious going for the relay. One successful boarding: Viola, your very own IFF. Accidently blowing up the ship... well, no rations for Cerberus on the other side of the relay then... another project to write off by TIM.
Really, the neighborhood is neither safe nor very isolated so while Cerberus may lock out everyone they might get locked in very easily, too. The only safeguard for the Collectors was that they were the only ones getting in and out, As this changes everyone will know that there's a way in and this is a lawless speck of space where none cares about Council laws concerning not opening mass relays just for fun this opportunity - esspecially when a known human terror organization or just any vessel passes through there freely it should get mighty interesting..
Part A) - as far as my (almost maxxed out paragon) Shepard who kept the base was concerned, she had dialogue option, where she explicitly told TIM, in no uncertain and less-than diplomatic terms that the Collector Base was going to be used according to her plans as a resource to fight the reapers and that TIM could either "follow her lead" or should better get out of the way. Finishing with her telling TIM to STFU and waltzing off-stage, leaving a glowering but thoughtful TIM behind, staring at the CB's hologram.
I will try to do a quick playthrough of the finale sequence and do some screeners for the precise phrasing and dialogue choices if there is serious interest (it's pretty lame that you have to replay the entire end battle and the "grand speech" scene to get to the TIM sequence ).
As for part

The O-IV relay is useless without the Reaper IFF. Yes the scum of the universe is living nearby, but the scum of the universe (in the ME universe) does not operate battlefleets or anything that could stand up either to the human (alliance) fleet or even to the Normandy SR-2 in upgraded mode. and Cerberus posesses Stealth-Tek and Emission control technology since they co-developed the original Normandy SR-1, which should make their "foraging parties" going through the relay rather hard to intercept or even observe for civillians or even the merc-groups. BTW, the mercs in Omega Space are pretty much in reorganization mode after the events of ME-2, with their local sub-chiefs having been shredded in the Omega missions.
And even knowing that someone is now sending ships through the Omega IV relay, with some possibly even returning does still not tell anyone what is on the other end of it,, how to survive going through or how to dislodge a cereberus or Shapards's own team from the CB.
Overall, I judged the end-sequence, even with keeping the CB, that after the successful attack on the Collector Base, Shepard is basically dragging the best and brightest of Cerberus (such as Miranda, a die-hard TIM Loyalist in the beginning ) to follow him or be swept aside into obscurity in the looming conflict. Which will seriously Cereberus, which anyway has invested a major chunk of its resources into him/her and the team. None of which I see going over to Cerberus and its huge (ahem 150 agents ?) army of operatives anytime soon.
And IMHO the Illusive Man is savvy enough to play along with the "winning" side to maintaina modicrum of influence and further Humanity's agenda. Which Shepard - as alluded to in the prologue - is the most likely pawn on the board to make a reality.... After all, TIM's motivation is ensuring and solidifying humanity's place as a major power in the galaxy, not vying for personal political power or glorification. And given Wilson's actions in the tutorial, even Cerberus may have some internal dissenson and factions vying for dominance.
YMMV
