The raspberries are floating because there is yeast in there fermenting and pumping out CO2. Once they're fully consumed they'll probably fall to the bottom. Having them not fully submerged will not cause problems. Here is a picture of yeast eating away at some cherries in a quad I brewed a while back (they started at the bottom, floated during fermentation, then fell to the bottom again after a couple months):
Dont open the bucket until you're ready to take a sample, maybe a year after brewing. Its a bit late now but I agree with not adding the fruit until a few months before bottling/kegging.
