If that is the way you are going (as opposed to taking lessons and learning theory), then I recommend learning songs. You know the song and you are forced to learn how to change chords quickly and at the right time. As you learn more songs, you will learn more chords. It is a much more rewarding way to learn than just learning chords, one after another. There is nothing to stop you learning chords independently if the mood takes you. You also need to practice changing from one chord to another. Eventually, you will need to learn and fully understand how chords relate to each other in 'families' (e.g. C, F, G7, Am, Dm, E7 ... and which of those often vary, such as G instead of G7 or Em instead of E7). Then you probably need to understand what makes a chord a '7th' or a '6th' or a 'suspended 4th'. Of course you can learn the chords without knowing why they have that name but it empowers you when you know how to work out the common variants for every chord. For now, playing accompaniment to songs you know is a good way to start.
