If you put the traditional leveling kit, 2", then it will sit slightly nose high. Any of the manufacturers that make levelinig kits will work, but you'll want to keep it to 1" if you want it level (most leveling kits are a 2" spacer for the front springs).
A leveling kit is traditionally used on an F350 to level the truck because they sit about two inches higher in the rear and the F250 is typically just about level. If you raise the front of your F250 with a typical leveling kit it will sit nose high since your truck is almost level (one inch higher in the rear). So, again, you'll need to make sure the shop installs a 1" spacer, not the normal 2" spacer. As an example, Daystar (a leveling kit manufacturer) doesn't even offer a 1" spacer.
You'll be able to fit a 34" - 35" tire. I don't know your wheel size (there is more than one stock size), but ultimately a 34" - 35" will fit (with or without the leveling kit mind you). Also, the diesel engine weighs more, so a truck will typically sit about an inch lower in the front with a diesel engine so that should be considered.

A 35" tire will fit on your truck without a leveling kit. A lot of guys on this site have done it without a problem. Most of the leveling kits I've seen for the '08+ model trucks say the 2" front lift will fit 37" tires, but you say you're interested in staying with 35" tires. Check out Ready Lift. I'm looking at one of their kits but don't know if I'm quite ready to tackle the loss of caster when these kinds of kits are used.
Currently, I'm running LT285/75/R18E (35"x11.5") without any lift on my factory rims. I use my truck off road pretty good and have not had any rubbing at all.
If you do get a leveling ket for the front of your '09 F250, you'll probably need to get a set of F350 rear spring blocks to replace your 2" blocks. Without the taller F350 blocks and the leveling kit, there's almost a 100% chance you'll be riding taller in the front than in the back... you know, prerunner style!

I was thinking that the 17" rims were under 8" wide.
That might be slightly under most tire manufacturers 8" minimum recommended width for a 12.5" wide tire. I may be wrong about the minimum width, so take that with a grain of salt.
That said, I have run tires that were wider than the minimum recommended rim width in the past without any problems, although it was on lighter duty applications than our Super Dutys can handle.
I looked at Discount Tire's website and found some common mud-grip tread tires. Surprisingly, a good old-fashioned 35x12.5R17 is fairly common in 17" rim sizes. However, not all of them are load range "E". That may be a problem on your 2009 model truck which has the Tire Pressure Monitoring System- if the tires have a max inflation pressure of less than 60psi (approximately) you'll forever be putting up with that little orange light and warning in the message center every time you start your truck.
Ugh.
Best advice is to check the load rating closely on a set of tires you're interested in. Heck, many shops won't mount a set of tires that are rated for less load than the OEM tires because of liability concerns. They don't want you to slap a law suit on them when you load up to max GVWR on a set of load range "C" tires on your F350. While you're checking the load rating of the tire, also take a peek at the maximum inflation pressure. Sometimes a "D" rated tire won't hold the higher pressures needed to keep the TPMS happy. (Mine trips under 60psi)
As far as decoding the metric tire sizes, for a 17" rim you need to be looking at something with a size similar to the LT315/70/17. The first number is the section width in millimeters. The second is the sidewall profile height (a higher number generally means a taller tire), and the last number is the rim diameter. This is seminaryranger's crash-course in sidewall decoding!
And because pics are all the rage, drool over your future set of new treads. Decisions, decisions... lol
Or for the ultimate in Off Road traction...
