I think the failure of the Orange Revolution will mean that Russia maintains good relations with the West for the foreseeable future. One of the main reasons Putin began his anti-Western shift is because he genuinely believes since at least 2004 that the United States has been pushing for regime change in Russia. He was convinced of this by the political advisors he sent to Ukraine to help elect Yanukovych in 2004, who after they came back to Russia created the theory of "Colour Revolutions" to explain their failures. ITTL Colour Revolution theory wouldn't even exist as a coherent concept, since both the Orange and the Tulip Revolutions failed (I think this might partly explain why Putin seeks a third term, as he isn't as afraid of domestic unrest).
On the topic of Ukraine, I don't think a revolution is inevitable. The 2014 revolution was very particular and hard to replicate, it essentially happened the way it did because Yanukovych kept shooting himself in the foot and fumbling every attempt at de-escalation with the protesters. Considering how badly the Ukrainian economy was hit by the Great Recession IRL, I think it's more likely that Yanukovych will lose in a landslide against some reform-minded candidate in 2010, probably some Tymoshenko surrogate or perhaps Vitali Klitschko, who ITTL was elected mayor of Kyiv in 2006.
