The height of the speaker's tweeter should be (generally speaking) at the level of your ear when you are seated. So it sounds like you nailed it. There some exceptions to this rule with tower speakers, however, where some have the tweeter higher than the listening position, but they have tuned the system to take this into consideration (Wilson jumps to mind as an example).
Try putting a string at your listening position and then measure that distance to your center channel (or one of the other speakers) and then take that string and measure each speaker. Basically, the string should touch in the exact same place on each speaker (front, center of baffle). If it doesn't then your speaker distances are off and that too will cause imaging issues.
A simple practice to get that accurate is to put a piece of tape on the carpet in right in front of your center channel (assuming center channel is directly in front of listening position). Then you measure from that piece of tape both left and right an equal distance to make sure that your L and R speakers are at the appropriate angle from your chair.
Then, take a laser level or laser meter and put it on top of the speaker and then toe in the speaker until it hits a specific spot on your listening chair. often you will find one speaker is not in alignment with another, another speaker is pointing UP more than the other, or any other oddity that only a laser can show. It will take you 15-30 minutes to do all that, but it will nail imaging and soundstage, etc. If your speakers are not in perfect alignment, the illusion of the stereo image will degrade.
Some will argue (and it's personal preference) that toe in should not be so harsh. If that's your preference then put a white board on a stand about 5-8 feet behind your listening position and then put a cross-hair target on it that you will try and use to level and aim both speakers. Remember, speaker leveling you should use a bubble level meter first. Otherwise, you cannot ensure which speaker is level and which one is not.
