Good general idea...
Please don't take this personally - but off to a bad start so far.

Done? Awesome.. Now... continuing..
"Throw together packages" are absolute crap. You get piece of junk gear that you're going to be replacing rapidly at that low low $250 price tag. So.. lets look into what is what:
1) Safety
Pretty much the only REQUIRED (not recommended) piece of safety equipment necessary is a well-fitting mask. If you fog up you can't see. If it doesn't fit well, it doesn't seal. Most any other part of your body you get shot, the item will bruise and repair or fix or grow back. Your eyes and ears don't have that luxury. You NEED to put money into a nice thermal mask - both for safety, and so you can have the best time possible on the field.
2)Reliability
Good call with the Azodin or Spyder Fenix. They're low maintenance, easy to repair markers that should take you all the way to your next marker without too many issues. They're pretty much identical though the Blitz's advantage is with its longer and autococker threaded barrel. The Fenix is cheaper, but already comes with a braided ASA hose, so CO2 is safe to use through the marker. Its pretty much a coin flip. Most stock barrels are sufficient...so pick based on color and if you're going to use CO2 ever.
3)Functionality
Your tank. A 48/30 is 48 cubic inches at 3000 psi. If a 68/45 is able to shoot almost a case off of a STBB (spyder or spyder clone), and an 68/30 would have half the usable volume of air...reducing the tank size to a 48/30 is probably 1-2 pods and a hopper. This goes to my mantra of "only buy things once". If you can afford it - buy your 68/45 tank. If you can't, you may be best off saving a bit more, renting for a bit, and getting this tank. Buying a 48/30...and then a 68/45 is going to raise your tank total cost to $200... and in some areas.. that's a case of paint.
Your loader - Same thing - Don't buy dumb ****, and have to buy good **** later. I'm not familiar with the Revi CAT, but if its anything like the Revi 9 or Revi12...its an agitator. Those work great if your marker is up and level and shooting around 6-10 bps. Your best bet is getting a nice force-feed loader with consistent ball stack pressure (read it again, giggle, and then take it at face value). SPending $50 now...to spend $80-180 later...doesn't make sense.
Pods are $2/ea for ANS generics.
I buy those swabs for $2.50/ea
And a jerk is going to run you $2
So - to start...
Fenix Blitz - $150
68/45 - $100 used/ $150 new
Halo Too/Spyder Fasta/Pinokio - 70/65/99
Mask - look at anything listed in Trbo's guide - $65-100
Harness - Empire had ones for $25-30 that weren't horrible
Don't look into pads, jerseys, pants, or any of the other frilly addons until you get this far.
So - less pods, swabs, and add-ons
$465 to get started. Yes, its higher than the $250 for the package - but you won't be spending money to replace gear within weeks of buying brand new stuff.
