My respec cost is sitting at 45g, and I still respec every so often. It doesn't take long to grind the gold for a respec if you want to or feel you need to.
Now your talent build. You want to tank, but you are missing out on 4 key talents, and investing in a lot of unnecessary ones.
Key talents you NEED are
1) One Handed Weapon Specialization
-5% more damage to EVERYthing. Some people think it just refers to weapon damage, but it increases your HS damage, your Ret Aura damage, your BoSanc damage your shield spike damge, etc.. etc.. which is more threat, which helps save your squishies and helps kill mobs/boses faster.
2) Combat Expertise
-The expertise isn't as necessary for you right now, though it will help in the future. The 10% extra stamina can and will help you. For you right now
that's another 500 hp, in the future it could be another 1000 as you get better gear. It's like having BoK up all the time... and then you can put up BoK again!
3) Deflection
-5% extra chance to parry. As you start to get better gear and you are trying to hit that uncrushable number, you are going to want to get every percentage point you can find. Parry is one of the best means of avoidance, because you take no damage when you parry. Something that as a tank you should be striving for.
4) Spell Warding
-4% less spell damage. Spells tend to hurt... a lot, and as a Paladin you have no way to mitigate that spell damage. Sure you can switch your auras around, but that's no guarantee, and it's definitely annoying. That 4% helps and it's only 2 talent points, so no reason not to grab it.
Talents you have but are unnecessary for tanking:
1) Divine Intellect
-As a tank, you will not be stacking intellect. As you replace your gear, you are going to see your +int go further and further down, and increasing your pitiful intellect by another 6% is not going to be doing you any favors. As a tank you get your mana by receiving heals, using blessing of wisdom, and/or seal or judgement of wisdom if you need it. In that order, and you should be fine unless you incredibly outgear an instance, which you won't have to worry about any time soon.
2) Seal of Command
-Bodh already covered this but let me reiterate. You need retribution stats like AP, Crit, Str, etc.. to make SoC work well. You don't have those, and Seal of Rightousness will outperform Seal of Command with your current setup.
3) Improved Hammer of Justice
-This one is a toughy. It looks nice, more stuns. And you use your stuns a good amount, so why isn't this good? I had a hard time with this as well, but as you start doing the harder instances and eventually start raiding, you will see that more and more mobs are immune to stunning. As I tanked more instances, I noticed that I disliked stunning mobs more and more, as you are not generating threat when they are stunned, because they are not hitting you. Save your stun for when a DPS grabs aggro and they are going to die and you <hopefully> shouldn't need to stun more than once a minute.
4) Precision
-You don't need it yet. You will want it in the future when you are raiding, but right now, at the content you are doing, Precision is not helping as much the other talents could.
5) Guardian's Favor
-Same thing... it's nice in Kara for fighting Moroes, and you might want to pick it up later, but if you are doing your job well, you shouldn't need to BoP someone every 3 minutes, 5 minutes is a good enough cooldown.
All that being said, here is a build that I recommend from experience and from seeing countless other Paladin tanks on these forums.
Here.
