1. U/R does not seem to have what it takes to top8 too much anymore, Why?
Personally, I love U/R.. but it has trouble handling oath, stax, workshop aggro, dragon and gifts.
2. Best color combinations? U/W, U/G?
They're really metagame dependent. U/W for controlish metas and U/G for workshopish metas. But they can both be tuned to handle both sides of the field quite well.
3. Cards that need consideration to be added to fish to handle modern decks?
Card choices range depending on meta and preference but they're usually hate cards. I play U/W and I prefer workshop and nonbasic hate since they seem to annoy me the most. Cards like Kataki, Energy Flux, or even Annul come to mind.
And I am sure there are more questions that need answering as well, but we will leave disussion to open those doors...

OK, first off, before anyone says anything, I have no P9. BUT, If I were to add power(say for a proxy tournament), what should I remove? IĀ have played U/W, and U/G fish also, but my own playing style seems to lean me towards playing U/R...
For U/R you want the standard Mox Sapphire, Ancestral, and TimeWalk. Mox Ruby is optional. It would simply replace your manasources.
-2 Wooded Foothills
-1 Mountain
-1 Island
+1 Ancestral
+1 TimeWalk
+1 Mox Sapphire
+1 Mox Ruby
If you wish to increase your mana count I suggest removing MisD and/or Stifle.
One big problem that this deck cannot handle is a resolved tinker for a DSC. I have no removal for that big assed S.O.B. (except yanking him from their deck with a thief). This is one of white's obvious strong points. White gives us meddling mage, swords to plowshares etc... Is a tri-colored fish deck say U/W/R feasible with all the maindecked non basic hate out there? What kind of mana base would be best suited for such a deck?
I've tried that before. Lavamancers with Mages. But it always seemed like it was trying to go into too many different directions, and with a much more fragile manabase you're pretty likely to get screwed by a couple of key wastes.
