Once you get your measurements squared away, you're going to need to cut your two-by-fours into the properly sized studs. Circular saws are hard to manage if you're not experienced, and you should save your trusty old hand saw for cutting branches. A mitre saw is the way to go, especially if you've never really used a saw before. This easy-to-use electric saw sits on a base with the blade attached to a handle that moves up and down. Simply measure and mark your wood, set it on the base and bring down the spinning blade for a swift and easy chop.
