Welcome to WMT!
I suggest you read
this post, which walks you through the general winemaking process. I've written
posts that go through facets of winemaking in more detail, with pictures that help illustrate points. These won't take long to read, and you should get a solid understanding of winemaking in general.
Further, download the MoreWine! red and white grape manuals (link is in my sig). Skim the white wine manual, as it's appropriate for where you are now. This goes into a LOT more detail, and you won't digest it in one reading. So skim it a few times. Before your next harvest, do the same with the red wine manual.
Keep asking questions -- it's easier to guide you onto a good path than it is to fix problems, and as you already know, you'll get good help.
When to bottle? That all depends on the wine. My general guidelines are:
whites, light reds, light fruits: 4 to 6 months
heavy whites, medium reds, medium fruits: 6 to 9 months
heavy reds, heavy fruits: 9-12+ months
Some really quick drinkers like Dragons Blood and Skeeter Pee can be bottled more quickly, but generally speaking, don't bottle before 4 months. Also note that the above times are guidelines, not rules. Each wine is different so you have to make judgment calls on things.
