Is this a good place to be at, a week into the challenge??

That would depend on how many robots you plan to build in a season.
For one robot, you're on pace, but my team's philosophy, is that if you're only doing one bot, finish a week to a week and a half early, so there's adequate time to practice your drive team, so don't wait till bag n' tag night to screw on that last bolt. An under-trained drive team is no good to even the best built robots.
If you're building two robots, you've got lots of overlapping projects and multitasking going on. I'll use my team's typical schedule as an example: Prototyping starts on day one, and is usually done no further than a week and a half in. During this period, the drive chassis is already decided (generally the design is decided before the season) which is a 6 wheel drop center, and is simultaneously being welded as the prototype for our ball manipulator is being developed.
After numerous mock-up systems made of wood, plastic, and spare parts, we begin development of the first robot by week two once we decide on a design, and the CAD model on Inventor is complete enough to start work. We consider this our practice/prototype robot. The benefit of a first robot, is that we can see any problems that can be fixed, so we don't make the same mistake on the second, final bot. The practice bot should be completely done by week four, and work on the final bot begins in the middle of week three, with chassis and frame welding going on at the same time practice bot is being finished. Because we already built one robot, making a copy is a breeze.
The final robot is finished in under a week and a half, powered coated, and tested for driving and used for practice. In the mean time that the final bot is in progress, the practice bot is used for the drivers, so they at least have a week to two weeks to practice, and when the final robot is done, we have our drive team A practice with final bot, and drive team B practice with practice/proto bot. We have two drive teams in the event that students cannot make it to competitions (for money problems or failing grades), or are MIA on lunch break (if they get one) at a regional.
Then we have a big potluck on bag n' tag night, where we show all the parents the twin robots, what they do, decide what is in our holding allowance, and then bag the final robot for competition, and keep the practice bot for more driver practice up until the first regional! Having an identical robot also means that you can fine tune a system that was in the witholding allowance. Just mount the system on practice bot, and tune it to the right configurations for both autonomous and teleoperated tasks, so you can literally extend your build season to seven or eight weeks. And then even more driver practice with the practice bot in between competitions.
We go hard with the drive team practice stuff now. They are the people who win your matches.
If you haven't seen it, check out Team701TV on youtube, and look up our 2013 build season video, you can see that we build a practice bot, and then a clean, professional final bot.
