>>Fellow bogie nuts
I think you can safely classify me in that category. 
>>I keep B.rosaliae and S.triaspis, are bogies easier, the same, or more difficult to care for? I have read some things about regurging etc...and want to avoid this.
I also keep both of the aforementioned species, and though I haven't had many problems, I'd say subocularis are still easier. Several of my suboc friends have kept Rosalia Rats and got out of them b/c of regurge problems but have done fine with the subocs. One thing you have to remember about rosaliae habitat is that it is drier than subocularis habitat. There is much less precipitation in Baja California in the Sonoran Desert than there is in TPRS habitat in the Chihuahuan. They're both arid, but Baja is much more so, in terms of amount of precipitation. Thus, the guys who have had the most success with Rosalia Rats kept the snakes on their top shelves in aquaria or super-ventilated racks with a warm basking spot. Soooo...I'd say if you're doing okay with the Baja Rats, keep the subocs the same and you'll be fine.
>>These guys are hatchlings, I was going to keep them up over the winter in well ventilated tubs, any tips on temperatures?
72 - 78 F on the cool end and 83 - 87 F on the warm end with a gradient in between the two ends.
>>Are they weekly eaters, more, less? smaller prey, appropriately sized, or can they handle larger?
Weekly is fine. They usually go smaller, but some can surprise you...still, not little "oinkers", as much as say, a bairdi or corn snake, collectively speaking.
>>Any tips or insight into providing the best for these guys will be appreciated!
Good luck with them...there's a pretty big book coming out about TPRSs soon, and also includes a chapter about triaspis, rosaliae, and bairdi.

p.s. Please let me know if you breed your Bajas.
