the outer tie rod is an easy job just about anyone can do but the wheel bearings require taking a few more things off the car. Your best bet if you want to tackle the job yourself is to take the entire knuckle assembly off the car and as said before take your new bearings and knuckle to the local machine shop and have them press out the old and press in the new bearings for you. Shouldn't cost more than an hour in machine shop fees($45 in my area). Your going to have some problems getting the axle nut off the car without the use of an impact gun, it can be done but is a big pain.
To get the knuckle off your going to want to take off the caliper and caliper mount, ball joint nut, axle nut, lower strut bolts, and finally your tie rod nut. After taking apart these things and sliding your axle out of the knuckle it will come off the car. A few good whacks on the knuckle might be needed to seperate the ball joint and tie rod. If your going to do the outer tie rod on the same side break the lock nut loose on the tie rod before you seperate it from the knuckle. Make sure you count your turns when taking the tie rod off to get your alignment back in the ballpark. It will still be worthwhile to get an alignment after you replace the bearings anyway since the knuckle will be off the car. Camber isn't adjustable but it can get a little off by tweaking the lower strut mounting point.
Its not a bad job but can be frustrating when bolts don't want to come off. Soak everything down with some penetrating lube(haha!) and let it soak before you start on the job. Having air tools will help a bunch but aren't a must.
