Hehe - that pretty much sums up what i would have said.  The shift from prosumer/compact to dslr cuts your macro ability unless you but a dedicated macro lens (and you have to go prime - i havent heard of a zoom macro that is any good - my 70-200 2.8 claims "macro" on the side, but my 105mm beats it hands down). 

The other thing is that in some situations your panosonic is going to outperform even a macro lens on a dslr just by the fact that the focus distance is insanely smaller and the resulting macro is often better.  I wouldnt swear by it, but it also seems that with a fixed lens prosumer cam you can get a better DOF for full bodied insect shots, i look at your macros and think it would be nearly impossible to get such DOF with my 105mm.

My advice would be to consider that you will just buy a dedicated macro lens and a telephoto zoom lens, and skip the wide angle for now. That is if you are plannign on following your shooting style i see in your gallery now - maybe just get the kit lens (18-55mm) -it is very cheap and decent enough as lenses go/for the price (in my experience of it - it is a very debatable subject tho) - just so you can shoot wide angle should the urge come over you.  I have the 105mm sigma macro lens and would recommend it, but thinking of it, you might actually like the 50mm macro as it would be closer to the shots you would get out of the prosumer and acts more like it in terms of DOF and use (working distance is shorter than the longer focal length lenses) - plus a 50mm 2.8 is always a nice bonus in any kit bag for use in portraits etc.
