boh lui oo... *waiting for bonus mode*    tis coming sun we exchange body for 1 hour ya... wakaka

i thnk kit lens also quite sharp ed. just need proper exposure + lighting

YES

smaller F number will do.
use as small iso as possible. use external flash to bumb iso.
YES. why you can't do it?

yes u can do. all u need is external flash. mine was using SB900 but for indoor with common (not too high) any flash will do. set ur shutter around 60 - 100, since kit lens, i prefer to stay it fixed at F5.6. then lastly set ur ISO with the situation. my condition there is low light so i set 800 or 1000 forgot ed.

if u flash bounce nicely, wallah there u gooo

yes aperture will effect the sharpness. kit lens will be sharpest at F7.1 - 9 IIRC but remember its all depends on what u gonna shoot coz some picture need bokeh and some dont need

yeah.. F8 will give you the sharpest one. more than that give you distortion (depends on the lens.)
Good luck on your shooting.

bounce it to ceiling. the shadow will looks cool.
else my friend usually put the flash behind the object and use commander mode.
it makes the subject seems like highlighted.

strobing aka wireless flash
