Sorry phoney - gotta disagree a bit with you, there is lots that can be done to improve where Rocky's at including:
replace the kit yeast either with quality dried eg SAF or liquid (try using the dregs from coopers pale - there are plenty of threads here about how to do it)
use 2 cans instead of adding brew enhancer
replace the brew enhancer / "converter" / blend with straight liquid malt extract (I remember doing a couple of canadian blonde kits with morgans amber malt which turned out well.)
steep some steepable grain eg crystal or carapils & add to your fermenter what you use will depend on the style....
steep some hops & add to your fermenter
mini mash (in a small 6 pack esky & strain through some voile or a clean B) pair of pantyhose & add to your fermenter - the wort not the pantyhose
)
bulk prime (if you're bottling)

Have a read through the k&K sub forum & the wiki - they both have top ideas. Also read up on AG brewing as you'll get a better idea of what is possible / how things work. John Palmers Howtobrew.com is a great starting point - it also covers extract brews like phones suggested.
Many here have gone from k&k straight to AG using BIAB for little outlay & using gear that can be used later if you decide to move onto a 3 vessle AG setup. so check it out too.
Catch up with the IBU's - you will learn more from talking face to face & dropping into a brewday than I can type here.
Get your basics under control ie sanitation & temp control (you shouldn't need to ferment anything above 20 so ditch the belt!!) & understand what you are doing & more importantly why. Do that & incorporate some / all of the ideas above & you'll definitely improve your brewing.
Have fun
