Speed and altitude deviation on the ANCHR2 arrival on the arrival phase into DEN the flight was task saturated due to atc. Atc had given us 3 different arrival procedures and multiple turns off course. While on a heading and abeam LIBIE we were given hold at LIBIE at FL230 and expedite down to 230. We were at about fl270.  We were about 4 miles from LIBIE and we needed to make a 90 degree turn to get there so we entered the hold manually and set up the fms once we were far enough away it would accept it. No problems there.  Later; after released from the hold we were about 3 from HIGUN and I reminded my fo about the speed restriction of 210 at HIGUN. he was still in manual speed mode from using it in the hold.  He then went full speed brakes to slow down and I don't think he was in fms speeds yet because the aircraft got slow.  He said he must have hit the toga button when he was going for the speed brakes.  The plane went into go around mode and started to climb. I shut the speed brakes and told him to watch his speed and altitude. I then took over the controls and got the speed and altitude back and set up the automation for him and gave him back the controls. I believe we got about 50 knots too fast and between 700 and 1700 feet high.  Soon after that we were on the localizer for 17r and the fms still had the arrival starting at ANCHR 3 times.  We entered icing conditions. I tried to clean up the flight plan in the fms and it wouldn't let me. I also needed to enter ice speeds and did so. meanwhile the fo (pilot flying) did not start the descent on the localizer so atc turned us off the loc and re sequenced us. I believe we were still about 15 miles out at that time. I believe the fo got very flustered after the hold instructions even though the hold went fine.  I think that led to an over reaction to the speed assignment at HIGUN.  I could have taken the controls sooner and maybe there would have been no deviation.  I was trying to talk him through the recovery but he didn't respond.   I don't really have a good solution.  I believe being comfortable with manual mode and not relying so much on the fms is important.  The fo didn't seem to have much situational awareness apart from the fms.
EMB-170 Captain reports being issued 3 different arrival procedures and multiple turns off course during arrival to DEN. Then; while on a heading; the crew was given holding instructions. The hold goes fine but later in the arrival the TOGA button is inadvertently pushed while attempting to slow and descend for the next fix; resulting in a high and fast crossing.
