I personally would pick Oceanic over Beuchat because I believe they have a larger worldwide dealer network so service/parts availability is probably better. At least here in the U.S. that's the case. I travel a lot in the western hemisphere and I see a lot of Oceanic gear used as rentals.
I assume because you're considering Beuchat you're not US based. It's not a real popular line here. If you have a nearby dealer, Cressi is also a good value for the money. Or SubGear - the lower end division of ScubaPro. Any of their dealers can work on either. They have some good pricing and I've been told SubGear regs are discontinued re-branded Scubapro models. You could also look at a Scubapro MK2 Plus - classic downstream design - if the reg fails, you'll still get enough air to breathe on to surface. With an R195 2nd stage they're $339. LeisurePro also has a Mk11/R195 for $369 - it's a lot better reg than the Oceanic.
Scuba Pro MK11/R195 Regulator 12.197.000 Same price everywhere - Scubapro sets it thru their dealers.
If you want the VEO with a separate hosed pressure gauge you can do that within the Oceanic line for $120 more also.
Here's my example based on U.S. pricing:
Oceanic SWIV Pressure Gauge Only, Metric 04.1377.07 - $109
Oceanic VEO 1.0 AIR/NITROX Wrist Dive Computer 04.3005.36 - $299
compared to the VEO 1.0 console which sells here for $389. As mentioned above, an $80 pressure gauge from Sherwood works just as well. Not much savings but it helps. Another option is the Hollis DG03 - Hollis is the technical division of Oceanic. It's $250 plus you can later add the transmitter for full Air-Integration for $329 more if desired. One thing some people do with a wrist mount computer is buy a small "brass/glass" pressure gauge and put it on a short hose. Those start about $60.

If you're not set on Oceanic, Dive Gear Express is salling the Zeagle N2Ition 3 computer for $180. It does more than the VEO but is probably a closeout. It's a 3-gas computer so could be used for more technical diving and also has a digital compass. i don't need one but will likely get one soon.

I don't follow Oceanic regs well enough to comment on your specific choices.
I suggest possibly a back-inflate BCD instead of a Jacket design also. Many people learn on Jackets since that's typically what they rented/used during classes. Many later switch to back-inflate designs. Of all my friends who dive - all have. One switched back to her jacket because she liked the bigger pockets. But as a DM she carries a lot of junk. In the Oceanic line that's the Excursion or the Atmos. If you mostly dive warm water/plan to travel look at a travel BC also. They're lighter, have less lift and fold smaller. Some to look at - Aqualung's Zuma, Hollis Ride, Scubapro Lighthawk or Zeagle Covert. All will be cheaper than the Flex2.
