I'd also ask about these areas:
1) What software development methodology do you use, e.g. Waterfall, Agile, Scrum, XP? This would be a big one for me that you left out though this may fall under coding standards.
2) What parts of the software development life cycle do developers do?
3) What is the breakdown of a developer's day, e.g. how much time for support or troubleshooting, how much time for coding, analysing requirements, etc.?
4) How are projects categorized, e.g. changes compared to a small project compared to a big project?
5) What kind of management is there within the company, e.g. is the development manager also the project manager or are these separate people usually?
6) What kind of feedback mechanism is there for determining employee performance, e.g. how often is my work evaluated and suggestions given on where to improve?
7) Is there a dress code? Do employees work a fixed set of hours? Is there any on-call time as part of the job?
8) Give me an example of a code review that is done here. Are there different levels of a review, e.g. new system is handled in a day long explanation compared to a quick bug fix that is needed ASAP.
9) How are conflicts resolved between testers and developers? I ask this because there have been times in the past where I see finger pointing of "Well, I interpreted it this way and he interpreted that," enough to make me ask how is this handled.
10) How are requests for large changes to be done quickly handled? For example, someone requests a web application that would normally take 2 weeks be done in 2 days for a prospective client that could be a big account.
11) Do you encourage employees to set goals and provide incentives to meet those goals? Is self-improvement a value common to this organization?
I'd also look to see how my questions are viewed, such as do some questions seem so typical that the answer is straightforward and it shouldn't be brought up yet or is there some discussion about what I'm asking, what kind of work environments have I worked that were good, what about the bad ones or at least bad practices at one.
Some of these may be simple or obvious but I like to be sure that when I ask a question it is properly answered as opposed to a "That doesn't happen here," answer for handling conflicts between developers and testers that do happen in most if not all places.
