It sounds to me like you may have air in the system, befor you dive into replacing the thermostat try bleeding the system. there are two bleed points , one under the TB and one behind the valve cover on the firewall.
Go to the library and read the DIY coolant flush
When there is air in the system it will give a false reading on the temp guage
You should get a radiator funnel, it has adapter caps and a spout to put the funnel in. You can run the car without having it overflow. I got one off the SnapON tool truck that comes to my work (35$) Not SnapOn Brand (generic) but was worth every penny.
I just used it two weeks ago when i flushed my cooling system and i never had to open the bleeder, i just filled it up till there was about a quater of the funnel full and i ran the engine for about 15-20 minutes lightly reving the engine 2 or 3 times.
The air will work its way out ( lots of bubbling in funnel ( its a good idea to place a rag over the top to keep it from splashing out )). Shut the car off and let it cool for about 10mins, plug the funnel with the plunger it comes with remove the adaptor and put the cap on and test drive
If that doesnt fix the problem then it could be the thermostat
Good Luck

The radiator cap says the system is under pressure when hot so doesn't seem like you can do that. What I do, after doing all the proper bleeding, is run the engine (with some coolant in the overfill container), let the engine hot, turn it off, fill up the overfill tank again, rinse and repeat until it stops looseing coolant.
