I actually got into the beta not too long ago myself, so I'll do my best to provide some answers here.
yay! we got a holy pally on the inside!
what are your cast times for Divine and Holy light in beta? If I remember correctly Im at 1.79secs on live. Curious to know what its like in Beta.
Oh, and judgements for holy, is it still the current model of 1 judge every 60 secs, or is it back to judging on cooldown?
did i read it wrong or is HR mana drastically reduced? I know actual numbers mean little right now, but still curious.
On beta, my cast time for both the Divine and Holy Light spells is 2.19 sec, whereas on live it's 1.94/1.95 sec (with and without a relic equipped, respectively) with Judgements of the Pure and 2.12 sec without. It's definitely noticeably slower on target dummy tests. Additionally, the haste rating to haste % conversion seems to have changed, as my 1809 haste rating (relic unequipped) grants me only 14.13% haste on beta compared to 17.55% on live. That looks even worse with the relic equipped and Judgements of the Pure active on live, as that nets me 28.45% haste.
Also, Holy Paladins still only need to cast Judgement once per minute to keep the Judgements of the Pure buff active. No need to cast it on cooldown. Just remember that the buff itself has had the haste portion removed, so it only provides mana regen now.
As for Holy Radiance mana cost, on beta it's currently 7000 mana to cast as a level 85 Holy Paladin with 102,000 total mana after normalization (unaffected by gear and Kings). Compare this to live, where it's currently 9369 mana to cast with a variable mana pool (in 392 average item level gear, mine sits at 130,705 without Kings and 136,060 with it). In other words, it takes roughly the same percentage of my total mana (~7.0%ish) on both beta and live servers. If you're better geared than I am the change may work against you, whereas if you're worse geared than I am then it favors you slightly.

There there, have a cookie. Well pallies get to make their charger shine with bright light, how cool is that!
Sadly the glyph effect is not yet implemented, but I'll do my best to take a screenshot once it is. :(
