Welcome to Librarium Online!
I am a noob with eldar right now so dont flames me if this is wrong or cheesy lol. couldnt you have an avatar in front of a farseer and just move him around the field easily (along with one other squad of something too) and even if the avatar fails his saves the farseer can let him reroll. Im pretty sure that would be a pretty big chunk of your points right there though and not very practical on an open field. the reason I say this is because we had a four person combat patrol and i was facing the warhammer veteran with his newly aquiered tau. it sucked because my dire avengers and farseer had to run straight at them the way the map was set up. so would this work? (taking a big chunk of points) and is this legal and non cheesy way to play?
Yes it could work (albeit it rather expensively and ultimately pointless) but not in combat patrol. Combat patrol missions have restrictions on the type of units you can take - nothing over 2 wounds is one of them (if I remember correctly) so the Avatar wouldn't be allowed. Other restrictions include nothing with a 2+ save, no vehicles with a combined armour over 33 (I think, not sure on this one so...) and a couple of others that I may be missing out.
As for dealing with tau - try and use available terrain or something fast like jet bikes or warp spiders, and don't forget to fleet with your dire avengers and farseer! Another handy trick to remember is that fleet ignores cover, so if he is hiding on the other side of a wood you can (providing you roll high enough) fleet straight through it and then charge him

I would never have done that for combat patrol lol. sorry should have said that better and I was using fleet of foot and it took me i think 2 turns to move within shooting range but i had only lost a few avengers i think. if I remember right i was rolling pretty well i was getting 6's for fleet of foot and i was saving them pretty well but when i did get up to his tau i had one dire avenger lol. I guess ill just have to keep playing the game to get better. thanks for the quick answer.
Also consider that the shield tactic you're describing could be easily countered by double flanking, or corner-anchoring. An ex-army friend of mine often anchors his two corners with a firebase each (tank, devastator or equivalent...). So using the shield tactic in the middle of the field is not possible. You could use it on a flank though.
Now, instead of an Avatar, I think a pair of Wraithlords would be more effective, because :
1. they could use their ranged weapons when (slowly) advancing,
2. the shield would be wider
also the Farseer + 2 WLs combo is a natural (to avoid Wraithsight).
But then, remember that a body shield of Guardians, or Dire Avengers, could also be effective...

I believe farseers also have to many wounds for combat patrol.
As for DA vs firewarriors you'd want to approach under cover if possible. It usually isn't.
But the key thing is to operat in their 18" range but not within tau rapid fire range. Meaning, unless you're just trying to charge, you'd want to fire at the extreme end of 18" so that you'll hopefully kill the firewarriors who could get in range if they move 6" closer to you.
Do that just right and you'll force the Tau opponent to either move forward for a weak rapid fire (probably followed by more shuricaning and a charge) or fire 1 shot per guy at the DA who are fireing two shots per guy.
Still unless you moved up under cover and got the first shot in fire warriors will outshoot DA. It's what they do. You'd need other units to take down the tau.
For example if you had some war walkers with longer range weapons (scatter lasers will do but tau don't like EMLs) you could pepper them from a distance. Then position the DA so they're hidden until they move out and blast away at any suits or firewarriors who try to advance in order to get a shot at the walkers
