Brew another batch and ferment it in the carboy... Start it in about two weeks, so that you'll be almost ready to drink the first one, when the second is going into bottles... Get some blow-off tubing (should be the same size as for the racking cane) and a 1-2 gallon pail (or other largish container) for the tube to go into. Half fill the container with StarSan solution (the smaller container) and put the end of the tube into it... The liquid creates an airlock effect, so that you can have blow-off/foam-over going into the bucket, instead of the walls. After the brew has been going for a few days, you should be able to pull the tube and install a standard airlock... I've done this a few times already, works great... Also means you can use all your fermenting vessels for primary, not designate some for just primary and others for just secondary.
IF you're going to need to rack off of a flavor element, to add another, then you'll want an empty vessel for it. But, you can use your bottling bucket as a temporary home for the brew while you clean what it was inside of. Just be careful about how you do it. Personally, I'd only rack when you need to halt flavor contributions from an element and you're not ready to bottle yet... I did this for a brew with a vanilla bean. Racked off of that onto some oak chips, where it's been sitting for the past few weeks... It gets bottled this weekend.
After you get the process down, or get into it, you'll want to get into a brew cycle... Right now, I'm going with about every two weeks, brewing a batch. That means that every two weeks, I start a brew. Either that week, or one on either side is when I bottle a previous batch. Since mine are staying in primary for 3-4 weeks, that works out well. You'll also want to have enough primaries so that you can brew those batches (figure a standard batch is in primary for 4 weeks) and still be in a good cycle. That could mean that you bottle the day before you brew, unless you get another primary for brew day, and bottle after it... Right now I have one carboy empty. I have a second that will be empty this weekend. I have grain coming so I'll be able to brew next weekend (won't get here in time). I have one batch that was bottled a week ago Sunday, and another batch that was bottled this past Sunday (two in a row)... I brewed a batch on Saturday, so I have one running, two carbonating, and will be brewing another in ~2 weeks... I'm also looking at brewing another on the 19th, but might wait since I need a primary for a brew coming up on the 26th... So the 13th will be better (have a party on the 12th, where I'm bringing home brew)...
Planning on keeping with the 2 week cycle from March forward (come hell or high water)... I'll have a grain mill by then, so it will be far easier... Especially if the group grain buy goes through, and I have a few sacks of grain here...
