I currently am running 3.73 gears on 33's could i get by on 35's?

What kind of transmission? What are you planning on doing with the jeep? What kind of driving on the street? Basically, thats where the problem will be. High range it'll be a real dog, and worse if you have much hilly driving to do.

You can probably answer your own questions. Just drive it without using low gear. That'll be an approximation of how it'll feel.

I have a 5 speed dont do much highway drving and am the occational weekend wheeler

So when you make all your starts using 2nd gear, how does it feel? Thats how it'll feel with the bigger tires and you using 1st.

i have been running 35's for 6 years now on my jeep and its an auto if that has anything to do with it, but i have 3.73 gears with 8.8 axles and pull two motorcycles all the time with it and have absolutely NO problem whatsoever..im actually putting 37 inch tires on mine tomorrow after trying a set from my buddy, and even with the 37 inch goodyear mtr's, my jeep pulled with NO problem at all and no bogging or struggle whatsoever....my buddy has a rubicon and reagears his to 456 i believe on 35's and mine pulls just as good as his and honestly couldnt tell much difference....on the trails, in 4low mine just creaps up anything i want it too, although im sure the lockers help that out,haha... not sure about 5 speeds though but if you have any auto youre straight!
hope my rambling helped
