Treble and tenor recorders both look like longer versions of the standard (soprano) recorder. Treble has a range just below soprano and wouldn't be too 'bass-y' for you. If you want to learn, though, try starting with the soprano because you can buy a reasonable one more cheaply and the fingering is virtually the same (although it plays different notes). You might also want to take a look at the 'low whistle' - a bit like an penny whistle but longer (and considerably more expensive).
Clarinet and alto saxophone are easier to learn than you'd think. The latter in particular takes less puff than you'd think too. The instrument does all the work for you.
