Yes. Both are correct, with a nuance:

… pour réparer l’ordinateur. (infinitive; shorter; the subject is implicitly Paul)

If I replace l’ordinateur with a pronoun, where does it go?

It goes before the infinitive: … pour le réparer. Full sentence: Je fais venir Paul ce soir pour le réparer.

Is réparer the best verb for a computer? What about dépanner?

Both are fine.

réparer = repair/fix (general).
dépanner = troubleshoot/fix a fault (very common with appliances/computers). Your sentence works perfectly with réparer; dépanner is also idiomatic: … pour dépanner l’ordinateur.

Can I drop pour and say Je fais venir Paul réparer l’ordinateur?

No—use pour. Without pour, it sounds ungrammatical or at best very awkward. French needs pour (or afin de) to mark that purpose here.

It can be. Context usually resolves it, but to avoid confusion keep one noun explicit or rephrase:

Je le fais venir pour réparer l’ordinateur.
Je fais venir Paul pour le réparer.
Or use the other causative: Je fais réparer l’ordinateur par Paul.
