Narrative:
On takeoff roll; the first officer's pitot gauges all flagged. We continued the takeoff. Once at a safe altitude; we ran necessary checklists; notified maintenance and dispatch; got a new clearance and release for ZZZ and returned. We planned for an overweight landing. Approach kept us fast and after dropping the gear and running the checklist which includes a recall check; we noticed the speed trim fail and mach trim lights illuminate on recall only. This distracted the captain for enough time to look up; evaluate; but get a little high on the profile. We opted for a go around. We ran all the checklists again and returned for an uneventful overweight landing in ZZZ.
