Is it? The Serbs turned against the Ottomans in hopes of gaining a secure outlet to the sea. Russia has just gone to war with Austria. A very good argument can be made that Serbia would be looking north not south...
They are trying to secure an outlet to the sea as well, however a more nationalistic plea to the population would of course be 'liberation' and all that. Serbia intends to 'liberate' its serbian territory before moving towards its 'yugoslavist' ideals towards the north.
You are writing an Ottoman TL understandably, but no way the Greeks would let the Ottomans gain naval superiority, particularly since they have no economic reason not to. By this time the Greeks will have their own pair of (likely US made) super-dreadnoughts. After all given the likely British-Greek alliance by 1915, the Greek navy is a needed factor in the balance with Italy and Austria-Hungary as well with the British encouraging it...
Not exactly. The Ottoman and Greek navies are on equal footing with each other as of this moment, more or less, however equal footing does not guarantee that Greece can win (neither does it guarantee that the Ottomans can win in a naval confrontation) however the chances for the Ottomans to win have become far greater. With the expansion of Ottoman dockyards, the Ottomans can reinforce the balkans through the black sea as well, which the Greeks cannot enter because the Darnedelle defenses, thus making Greece doubtful of its ability to stop Ottoman reinforcements.
Is it? The Ottomans offered more of Epirus, including Ioannina in 1912 if memory serves. And since both Lemnos and Lesvos are out what north Aegean islands are we talking about? The Sporades are already Greek. IMO Lesbos, Samos and Chios coupled by provisions that they remain demilitarised looks pretty reasonable.
For the moment, gaining the important port of Preveza, the chokepoint of the Tymfala Corridor and the reversal of humiliation of 1897 by gaining the territories back are more than enough for nationalists *for the moment* however yeah problems will arrive in the future.
If I may propose another term, by now the previously mentioned British-Greek negotiations for the transfer of Cyprus in exchange for naval basing rights in western Greece should be even further along and with both Italy and Austria Hungary at war with Britain just became much more urgent... for the British. Ottoman consent wouldn't hurt...
The British will bring that up in the future, trying to butter Greece up to join the entente. Saving that part for the future.
