3. JPEG is not your friend if you want control over colour, exposure or even editing in general. Buy a bigger card or two.
4. Landscape and street are very different unless you really mean general travel photography? A full frame camera is better for landscape work but you may not appreciate the weight with a corresponding lens if carrying around all day.
5. Your lenses will all need to be replaced if you go full frame (which may not be a problem for you)
In terms of lens upgrades...... Are you after a "do it all" zoom, a Tele zoom, a wide angle zoom, prime lenses...?
I have recently rediscovered my little 35mm and it's awesome. Shooting in raw I have knocked out super crisp images and if I can't fit it all in I can just shoot a panorama and stitch it in Lightroom.
