First, don't go it alone. If you can't find a few friends that you can convince that you are on to something with whatever product ideas you have then you aren't on to something.
Software development is a team sport. Even if the other players are you in 6 months. Have coding standards. Have have your IDE or some program enforce them. Write documentation. Use version control. Use a bug tracking system. (Yeah, all that stuff you've read is best-practice... it got published as best-practice for a reason.) As a startup select a "major" language but for scripting just accept that any of perl, python, ruby, bash are fine. Train, mentor, and grow your people. You want really good generalists at this stage and not experts that can't also do ops, admin, front-line, etc. Using open-source software is a force multiplier. If you are going to extend OSS just make sure that your product value is in the data you are generating and not the code (since you'll be giving the code away for free).
You'll want to find people at least as good as you are for raising money, marketing, sales, product development, and IT (assuming you'll be CTO/VP Eng and leading development; if not find a CTO [tech strategist to put in front of investors and give you something coherent as far as technology goes], and/or a VP Eng [developer+manager who can wrangle the cats and makes sure product gets delivered when product is supposed to be delivered]. Coming from the tech side of things do NOT undervalue marketing, sales, and your CEO. The better mousetrap will not sell itself. At the same time while a great sales guy can sell snow to Eskimos they won't pay a lot for it. Find/build a team that covers each others weaknesses.
Gonna stop here. Could go on like this for a while since this is what I've been living the past 4 years.
Blogs in no particular order: Joel on Software, Paul Graham, any other 2-3 of the top tech incubators in the country (Google em).
Finally, ignore anything above that doesn't make sense for the business you are running.
