First, you do not need the 8-55 and the 18-135. Pick one, be happy. If you are going to get the -135, just do it and skip the -55. If -55 is enough, get the kit with the WR 18-55 and enjoy. The 18-135 is the better lens, but not by a huge margin. I'd opt for the 18-55 and spend the extra on a nice prime. If you really need the WR of the 135, get it later, get a prime first. If you want an auto focus prime, the DA40 is a cheap(ish) way into the Limited cult. They really are much more fantastic to own than what everyone says. If my wife would let me, I'd sell our children to finish my DA Ltd. collection. Or you could start with the DA35 f2.4. Cheap, and the images from it are stunning.
Another tip for you is to go into the menu and enable the aperture ring. It's off by default, and you will think your camera is broken. Also, some old lenses have paint on the mount, and that won't short out the contacts on the mount, and it won't register correctly.
Manual focusing: My first prime was a cheap A50 f2. Not the sharpest lens in the world, but good enough and cheap. Still an entire universe sharper than either of the zooms you are considering. Taught me that I love primes, and that manual focusing isn't so hard as long as your subject isn't moving around quickly and you are patient. If you use a K, M or A lens, you can use catch-in-focusing. Some love it, I don't get much use from it. The thing about digital is you can shoot 20 frames and only keep the 1 or 2 in focus. You get focus confirmation with the little hexagon anyway, so you can use that as a poor man's auto focus, just your hand is the motor.
I bet you can find a forum member in the UK that would sell you a 50 f2 for practically nothing, if you were on this side of the pond, I'd let you borrow mine for the cost of shipping. Gets your feet wet anyway. 50 is too long indoors, but don't let that slow you down from trying it out. Just don't be surprised when you're smashed up against the back wall and everyone still looks 2 feet too close.
The Helios is magnificent, and it will render differently than any other lens you have. It's nice to have a different flavor once in awhile. One thing about the Helios I love is the preset aperture. It really makes me slow down and think about exposure. Another serious bargain lens is the Super Takumar 55 f2. Much cheaper than the f1.8: but it's the same exact lens with a stopper to keep the aperture slower. I just picked one up and so far I like it more than my Helios 44-2. One thing to realize is that i ADORE my Helios, so that's really saying something!
Here's my favorite shot so far with the Super Tak:
