Would I be able to buy cartomizers from Smokeless Image and use them on the stuff I already got?
That would be breaking the loyalty program and Lifetime Warranty agreement with SmokeStix.
Seriously, I'm not sure. Smokeless Image uses the 808 threading for their batteries and juice carriers and they make no attempt to hide this fact. I have no idea what thread (510 or 808) SmokeStix uses, I saw no mention of this on the website. Some companies actually go to the trouble of adding a pecular threading to a commonly used one in order to force you to stay with their products.

I agree with The Ocelot, the kit that you have on the way will get your foot in the door of vaping and possibly help you to decide if you will like vaping. A simple disposable e-cig from a gas station or convenience store such as your Blu would do the same.
It's just that there are two tiers of e-cigs brands that are out there vying for your beginner vapors' money.
Some are legitimate companys that make a quality line of products that are reasonably priced. The others are ripoffs that put a lot of money into their advertising budget that make questionable claims, yet put out an inferior overpriced line of product and keep you purchasing with them with unnecessary restrictions that only serve their own purposes.

If you are still under the 30 day money back guarantee of satisfaction, I would seriously try to get out from under this companies grasp. My guess they will throw some roadblocks into your getting that money back, but at least you wouldn't be wasting more money on them in the future.
I would not even open the package when it arrives if you chose to take heed of my warnings. You will likely be charged a processing or restocking fee if you choose to return it, so you likely will not get a full refund back. Contact the company and advise them that you have chosen not to use their product and find out what their return policy is. Your best bet may be to just suck this up to experience, cut further losses, and find a better vendor.
Any experienced vapor here on the forum can give you better recommendations of product and juices and keep you within a reasonable budget.
The kit that you have ordered is extremely inadequate to expect to quit and stay off of cigarettes. You need battery time to last you for the entire awake times that you will be vaping. The single battery that you will be getting will last 2-3 hours and then need to be recharged. What will you vape with while that single battery recharges? Whether you correct that with more batteries of the same, or go with another company that offers longer lasting batteries is up to you to decide. The cartridges will last most likely half a day each.
The "average" vapor consumes 3-5ml of juice daily. Considering that a pre-filled cartridge can hold 1 - 1.5 ml of juce, you do the math.
