I agree with most everything you said except this. What size batch a vial is intended for is irrelevant. What matters is the yeast pitch count given the gravity and volume of the wort. An expired vial in a 1.5 gallon batch may actually not be enough yeast. You can play around with pitching rate estimates at yeastcalc. It depends on the original gravity and date on the vial (which is used to determine yeast viability).

I usually use mr malty, I'll check out yeast calc. For his beer, for that volume and that yeast it is an overpitch and 1 vial would be fine for 5 gallons, unless he's over 1.060 which I wouldn't think he is.

You're probably right. However, the original poster only provided us with the volume, you still need to know the original gravity and expiration date on the vial to say that definitively. A three day fermentation is fast, but it's a small batch and was fermented hot.

To the OP, it's a good idea to make a starter when using expired yeast. It'ss also good practice to know your pitching rate beforehand and make a starter accordingly.

Also I was hoping for a bigger bannana flavour will that come as it mellows out?

Big banana flavor with WLP400? That's not a main characteristic of that yeast strain, http://www.whitelabs.com/yeast/wlp400-belgian-wit-ale-yeast. Perhaps you are confusing a Belgian Wit with a Hefeweizen?
