I'm not exactly sure what you're asking so I'm just gonna throw out a few things:
On the bar clamps just below the ignition switch there are four M6 bolts that secure the handlebar to the upper triple clamp, but they're hidden under chrome covers. Just gently (they're chromed plastic) pry up the covers with a pocket knife or small screwdriver.
I personally wouldn't concern myself with saving the grips. They're about $10 to replace so you could just cut 'em off. If you want to reuse them wedge a screwdriver in under them and shoot some carb cleaner in there. Wiggle the grip around, repeat until it slides off. Carb cleaner is also good when you put them back on; a little shot acts as a lube and then evaporates leaving the grip tight.
$45 is a lot for a handlebar. $15 or $20 is more like it (Bikemaster) or eBay maybe. If you really want to spend the money you could step up to Suburban Machinery bars for $100 (IIRC); they are highly regarded.
Before you lay out the cash for clip ons, jump on your bike and imagine grabbing bars that are 4 to 6" lower than the stockers. Oh and you'll need to rework (shorten, flip, cut and weld etc) or replace your headlight brackets (the steel part, not the aluminum triangles) since they will be in the way of the clip ons.
No big deal, but if you buy anything other than OEM Suzuki bars (or SM bars, maybe) you'll need to drill locating holes for the switch pods. The pods have a little plastic anti-rotation pin that mates with this hole to prevent them from slipping. If you just cut the pin off the switch pods will most likely slip.
Hope that helps out a little.
