Here's a list of what we're growing now in the front, how it's doing, and how we're modifying things for the future.
Tomatoes: As you can see in the picture above, most of the front garden is tomatoes. They're a frightful mess. Essentially we tried to support them on strings attached to copper pipes. The strings stretched, the pipes bent, and I eventually gave up on trying to keep them upright and separated. So now they're all running together. I'm not too worried though. They're actually still producing pretty well (with some time off for insufficient water in late September) and don't seem to have too many problems. I wish I had weighed all the tomatoes to have a yield on the area, but essentially we had just about enough tomatoes for general eating and whatnot. A few extras went into sauce, but for the bulk of our sauce I had to buy seconds from the local farm. They were not the best sauce tomatoes, but $6.00 a half bushel is a fairly good price.
Next year this whole front garden area is going to be replaced with two raised 4'x12' beds. That should slightly increase the area for tomato plants and should significantly increase yield. As it is the tomato plants get almost no drainage. That means we had root rot early in the season, and as such ignored when they needed water late in the season. Even with the mulch it was a big mess. Basically next year we're planting the same verities (Lemon Boy, Mortgage Lifter, Roma, some cherries and a few others) just raising the bed.
Peppers: You can't see them in the picture above because they died. Root rot I think. They just wilted away during a wet spell and never recovered. They're moving to a square along the side of the house next year.
Squash/cucumber/luffa: They were planted to the right of the tomatoes
this year. Last year we did the same thing and the cucumbers thrived. We made 5 gallons of pickles. This year I think the cucumbers dried out. Essentially I was so afraid of root rot I didn't water much at all. Mistake. But the Luffa did ok. There's a picture of a young luffa fruit. It's a bit late for them (October) but they might have time to get mature. There are a lot of them on the plant. Supposedly they're edible and tasty when young. We'll see. In the meantime the unused west side of the house is going to get all the viny crops next year. With a hill it'll drain well and there'll be room for all the plants to really spread out.
Marigolds: We usually interplant marigolds everywhere to keep the rabbits and bugs away. It might be an old wives tale, but we like the flowers and they're great on salads so it doesn't matter whether or not they actually repel critters. They're just nice to have. Usually they're the normal dwarf marigolds you see everywhere, but this year we got a ridiculously large, out of control, mutant marigold. Our friends at Paradise nursery tell us that it's an old fashioned barn Marigold and that all the ones you get today are dwarf. Supposedly only the big ones have enough oomph to keep the bugs and rabbits away. I can believe it. I'm sort of scared of that Marigold.
Eggplant: There is an eggplant in the middle of that mess that is a front garden. It grew poorly and currently has one fruit on it. We seem to have very bad luck with eggplants. I assume it's just the normal root rot/lack of water problem that the tomatoes are having, and if that's the case then they'll be fine next year with the raised beds.
Grape: There's a 2 year old Concord grape in the background. It has a woefully inadequate trellis that's going to be replaced next year. It hasn't given us any fruit, but next year should be the magic year. I hope. 
Well, that's about it for the front garden. There are usually various containers on the sidewalk, but I'm not going to get into them right now. Thing to note is, the front garden is going to become two 4'X12' raised beds. This should make for some really productive spaces. I'm looking forward to it.
