Your plan is fine.
If/when you plan to up the boost don't use boost T get a decent boost controller (eboost street or eboost 2 for example) they can be had for a couple of hundred bucks secondhand and will work perfectly with your intended setup.
Turbo Tmap is not a straight plug in, the pin out is slightly different so you will need to change that. The pinouts are readily avaliable on the WWW.
Don't bother with turbo pcm/loom/etc add significant cost for no real benefit in a conversion such as this.
