On our (old model) we plugged it into the tape drive for power and the diskdrive interface port for coms.
I've only used an SD2iec once and I recall using DOS Wedge on the BASIC startup screen. http://ilesj.wordpress.com/2010/10/04/t

You'll have to mount the disk image on the SD2iec then power off, put the cart in, and power up again as far as I can guess. Personally, I use a second C64 and an 1541u to do my saving and loading with the MSSIAH. Looked at doing the tape load / save thing but it really was just too hard and buggy!
Yes, you just use "Load" and "Save" from the menu and it works fine. :-)

Hahahaha.... yeah. I'm up around $5000 on hardware between flash carts for about 8 platforms and things like Lynx dev kits, etc. The MSSIAH cart is the one thing I've hardly ever used. I used it once for a show, and accidently hotplugged something while I was setting up and blew up my SID chip. I only ever use it in the studio now - maybe once a year - and just sample myself noodling around.
So on that front be super super careful when plugging ANYTHING in or out on the C64 with it powered on and off.
