Dodge is a 3% miss chance, Displacement is 50%. And Evasion... you see lightning bolts in the Harbor 2's on Elite, so you can't have that "too early". Meanwhile, Precision cuts Fort by 25% - but you don't see a whole lot of Fort until later.
So I'd suggest...
First, since you are not taking any Fighter trees, we don't "need" Fighter 6 - 4 is enough, and that gets us Ranger 14, which gets us... Freedom of Movement (plus another Lvl 1 - Merfolk's?). Not until Lvl 20, but it'll help while farming those tokens.
But, a lot of TR's are really built to Level 18, so... I've got 2 diff skill progressions below, 1 for Fighter 6 (that gives us Extend at 18), and one without. Split the diff re Level 18 goals if you want.
Either way... we dump Int and Concentration, and take Quicken for no-fail heals, bumping that Str up to 10. (That won't help w/ scroll use in later levels, so if you hate it, shift it back, np.)
Delay Dodge and Mobility. Take the DM Level 3 (Invis is an "easy button" early on anyway), even tho' you won't have the AP for full Displacement until later. Then Beeline to Ranger 4 for Precise Shot and your first spell (CLW?) at Char Lvl 5.
Then get that Precision at Level 6, once you need it, and grab Evasion right after, Character Level 7, tyvm.
Then straight to Rgr 6 for Manyshot at Character level 9, bam - and
then you can start playing around w/ bonus Fighter feats. (This gives you Improved Critical 2 levels earlier than your proposed plan.)
(You've done PL's before - ever w/ a starting Str 8? I find it a real pain, so I'd go at least 10 Str, dropping Wis to 10 if I have to, but ymmv.)
If you prefer, put any/all Swim (and additional Open Lock?) ranks into Balance. I honestly don't know if only 4 ranks will help or not after low-levels, but Balance is a Dex skill, so... maybe???
