I recommend doing a case study and fully tracking all expenses. You can go backward in time and get a rough estimate of categories if you use a credit card on most things. It doesn't take that long, it's what I did when I first started. You can use a simple Excel or Google spreadsheet if that lowers the barrier (no need to use/learn a budget/tracking software). What an eye opener it will be (it was for me). That way you will know where you stand and where you can cut. Right now there are a lot of categories unaccounted for. I agree with some other posters, the restaurant budget should be 0 right now, phones are really high, groceries are highish (depending on where you live).
You don't say what your net take home pay is, but your combined income with your partner is 230k. That is a ton of money. Using an online tax calculator that uses California as a basis for state taxes, it tells me that on a salary of 230k, with no retirement withholdings, your yearly take-home is over 146k. That's 12,200 per month. The items you have listed above come to something like 8,500 per month, so that is nearly 4,000 missing. Obviously this is an estimate. But if you could account for that missing money (and/or go on a SEVERE spending diet for a few months, ie no new ANYTHING!!!), plus trim a few of the categories above, you could knock down CC2 in probably less than 3 months, and then snowball into CC1 and get rid of that one in less than 3 more months. At that point you have a lot more breathing room, and sure throw your bonus at the Lending Club loan, even though it is mathematically inferior, because it improves cash flow a LOT. At that point you could relax a little, not be so strict on budget, since you can easily burn out with severe restrictions.
These are obviously estimates since you haven't posted a full case study.
It would be difficult, you would have to really want it, but very worth it.
