Not nessisarily. I have seen foamy bubbles in lots of cooling systems that have not had head gaskit problems. It could be as simple as a slightly loose hose in the system or a leaky water pump sucking air in. I would get it to a Rad shop and get them to do a leak down and carbon monoxide test on the system before getting too worried.

As for the other noise i couldnt give you any real advice without hearing it sorry.

I agree, don't go ripping heads off without being sure. The squeeking noise could be coming from the timing belt/tensioner/idler.
