Learn to think of Home Depot and Lowe's as your new toy store. My first house was an old bungalow too that had been remodeled but it still needed some TLC. Get a few books and pick it up as you go. Easy stuff first. Replacing/putting up fans, then move forward. The list is never-ending...but I find it sort of fun. And know what you will never, ever attempt. For me, it's gas work. For others its plumbing or electrical. Then let the pros deal with those areas. Didn't have a home warranty but can see the benefit of one, even if it has been remodeled. I also would recommend the ac/heat service plan. It's also a good thing to have on hand when you end up selling in the future to show you kept up with the maintenance and they aren't getting a lemon.
I'ma going to go ahead and guess that's your car with the driver's side door so awesomely shoehorned in beside this vehicle. Reminds me of the time in undergrad at a parking garage people* parked so close on both sides of my car I had to crawl in through the trunk.
