an exciting assortment of brewing related questions

I'm moving on from kit brewing to partial mash this weekend. Going to brew a kolsch (sort of, putting in extra hops though);

pale malt extract,
munich malt (grain)
pilsner malt (grain)
spalt hops
riwaka hop flowers (which i have heard awesome things about!)
wyeast kolsch

Now, my kits have been good so far. A nut brown ale and an IPA i added extra hops to. But, my problem is i find they lack body or 'mouth feel' and there is a certain wateriness to them although the abv and general maltiness is fine. I'd like to avoid this with my kolsch.
Will adding mashed grain improve this?
If not what can i do? I have heard gypsum helps.
Also,does anyone have any advice on infusion mashing. i.e does it work?!

Cheers

You can't use the Munich or Pilsner malts in an extract brew. You'll have to mash them.

Yes, that's what i am doing. i am mashing the grains and adding the wort to the brew.

mouth feel can be improved with adding things like wheat malt, torrified wheat flakes (some have said even rice flakes) and the like.
