Ianto would be suspicious at first, but not necessarily hostile. (He's immediately suspicious but not immediately hostile towards John, who rapidly earns his ire and doesn't get forgiven even when he turns into something approaching a good guy.) A lot of how Ianto treats the Doctor will depend directly on how he treats Jack. If he treats Jack the way he did in Utopia, well, game on. If he treats Jack with kindness and respect, Ianto will treat him with respect.
As far as Canary Wharf, depends on how well Ianto knows what happened...whether or not he knows (or knows now) that it wasn't the Doctor's fault what happened and that he did the best he could in a very bad situation. I don't see that being a problem; one might assume that he and Jack have, you know, discussed the Doctor at some point.
The TARDIS will love Ianto immediately and give him fresh hot coffee as often as he wants. The Doctor will be vaguely annoyed at this.
