You smoke 2 packs of what kind of cigs? If 2 packs of ultralights, 24mg will probably be too much. I assume you plan to vape at least as much as you smoked? I smoked 1.5-2 PAD of lights and was able to start on 18mg and I vaped about 1.5-2 PAD worth of it.
When you say 5 count of blank cartos - do you mean 1 5-pack? That will not last 2 months. When you start out you might singe a one or more before you get the hang of filling etc. And I can get a week or a bit more out of a carto but I am vaping 2 ecigs. So I am really getting 1/2 week out of each - I could probably use one longer but they get a bit weaker. If you mean you got 5 packs of cartos, I recommend making one of those a pack of Coolcarts so you can try them. And get a delrin or plastic drip tip, either there or elsewhere (KR808D-1 drip tip - I got mine at LiteCigUSA.net). Occasionally a carto is hot and the drip tip makes a great cool and comfortable mouthpiece, and is also real easy to pull off for adding juice (don't drip into it - the juice would probably air for the air channel)
I recommend manual batteries especially with cartomizers and refilling. Safer from juice leaks (not dependent on a drag sensor in the threaded end of the battery), less work, more control of your drag, and won't turn on accidentally from wind or vibration.
I believe you will be offered your choice of a 5-pack of prefilled cartos at the end of your order (since you bought a kit) but they don't seem to list all of their packs where you get that choice. I don't know if the WOW samplers are on the list and blank cartos were not on the list when I bought my kit there. If they offer WOW Vanilla cartos they are pretty good and your cappucino would be an interesting refill for them - it would be a vanilla cappucino for a while then eventually be all cappucino.
And if you can use a charger at work, consider a spare charger cable. You could use a computer's USB. I ended up finally buying 4-port 2amp USB to AC adapters - one for home and one for work, so I can charge up to 4 different batteries (or 3 batteries and a PCC) on one brick. (I bring 2 PVs to work) I got mine at NewEgg - Rosewill 4-post USB to AC Travel (they used to have a US-only one but now just carry the one with US and other AC plugs). And there is one from Walmart that people recommend.
I think you will like it!! I love my V4L KR8. I like it so much I started using blank cartos on my 510 too. I eventually went from tobaccos to vanillas and chocolates with a bit of tobacco. I usually have Vanilla in my KR8 carto (or some prefilled flavor being refilled with vanilla) and in the 510 carto a mix of WOWbacco or FreedomSMokeUSA Cocoa w/ Backwoods Brew Casablanca (a complex Turkish blend w/ some cocoa).
When you first fill one, fill it well and let it sit for a bit so the juice will soak into all of the stuffing, else you run a chance of singeing it. I usually lay it or rotate it different ways to get the juice to all sides.
And some people are successful and cleaning them and getting more use out of them. I have a little pile saved up and will be trying cleaning soon.
