Yes, the 105 rings are removable. Every decent crank made these days has replaceable rings.
That crank is a 10 speed model though. As far as I know, it requires a narrower chain, and a new front dérailleur(FD). 38 teeth is the minimum chainring. I believe you need 10 speed chainrings though too if you wanted to replace them. It's always best if you can get the rings you want on the new crank to start with.
That's why I suggested the Sugino. It uses a 7,8 or 9 speed chain. Uses any FD designed for 5,6,7,8 or 9 speeds, including your current one. It's more universal overall.
I'm not a fan of Shimano and the like for constantly making parts obsolete. It really makes it a pain in he arse for average user.... and for a complete novice.... a train wreck because the parts have become too specific and proprietary.
