I think for any serious use, the 128Gb drive is simply too small, and most users would find it too constraining. On the basis that you can never have too much storage, I'd go for the 256 SSD, because upgrading it later would be much more expensive that getting it up front. Otherwise I'd agree that for anything less than serious heavy-lifting work, an i5 system is more than adequate.

'Serious use' in this context would typically mean photo and video editing, perhaps video encoding - applications and tasks which demand heavy processing pwer, lots of memory and high speed.
Very few users actually need a system capable of this kind of level of work, and from your outline, you would not be amongst them. There's always an argument that says you should buy the most poerful system you can afford, but realistically most buyers don't need anything like the power of the systems they own. The kind of task that you describe (including iTunes music for example) are easily within the capabilities of recent systems, let alone current models.
In short, you aren't likely to need an i7 processor.

The 256gb SSD is pretty necessary, photos and especially movies and videos take a LOT of drive space these days. Music is pretty portable, in fact I have gone over to iTunes Match and find it is a very good way of handling that aspect of my storage. Same for 4gb ram, while the SSD is fast and memory swapping works well with it, nothing can replace adequate ram. The processor speed is the only real option IMHO, the i5 is likely fast enough for what you have listed, but if you would like to get 3-5 years out of your purchase, the i7 won't be regretted.

Most people get by just fine with what Apple ships. That means if you have to ask then you most likely don't need it. Consider that the 11" ships with a 64GByte drive so 128 should satisfy most people. Mostly it is people doing video that need lots of space. Figure 8GB per hour of high def.
FWIW my iPhoto library has just under 4000 photos and takes 23GBytes. 900+ songs in iTunes is 4GBytes.
The i7 tests just 10% faster than the i5.
That being said, if you have the money then go for it.
